Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021008, here are decompositions:

  • 7 + 1021001 = 1021008
  • 11 + 1020997 = 1021008
  • 17 + 1020991 = 1021008
  • 19 + 1020989 = 1021008
  • 29 + 1020979 = 1021008
  • 31 + 1020977 = 1021008
  • 41 + 1020967 = 1021008
  • 47 + 1020961 = 1021008

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 1008 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1008-02-01 (DMMYYYY (Euro, single-digit day))
  • 1008-10-02 (MMDYYYY (US, single-digit day))
  • 1008-02-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,021,008 and was likely granted around 1912.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1021008 first appears in π at position 235,946 of the decimal expansion (the 235,946ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
