Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012138, here are decompositions:

  • 5 + 1012133 = 1012138
  • 41 + 1012097 = 1012138
  • 59 + 1012079 = 1012138
  • 89 + 1012049 = 1012138
  • 107 + 1012031 = 1012138
  • 131 + 1012007 = 1012138
  • 191 + 1011947 = 1012138
  • 311 + 1011827 = 1012138

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 2138 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 2138-10-01 (MMDYYYY (US, single-digit day))
  • 2138-01-10 (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 1,012,138 and was likely granted around 1911.

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

Position in π

The digit sequence 1012138 first appears in π at position 845,689 of the decimal expansion (the 845,689ordinal-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.
