Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026680, here are decompositions:

  • 3 + 1026677 = 1026680
  • 7 + 1026673 = 1026680
  • 13 + 1026667 = 1026680
  • 19 + 1026661 = 1026680
  • 97 + 1026583 = 1026680
  • 103 + 1026577 = 1026680
  • 199 + 1026481 = 1026680
  • 223 + 1026457 = 1026680

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 6680 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 6680-02-01 (DMMYYYY (Euro, single-digit day))
  • 6680-10-02 (MMDYYYY (US, single-digit day))
  • 6680-02-10 (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 1,026,680 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 1026680 first appears in π at position 669,406 of the decimal expansion (the 669,406ordinal-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.
