Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139864, here are decompositions:

  • 3 + 139861 = 139864
  • 167 + 139697 = 139864
  • 293 + 139571 = 139864
  • 317 + 139547 = 139864
  • 353 + 139511 = 139864
  • 467 + 139397 = 139864
  • 503 + 139361 = 139864
  • 521 + 139343 = 139864

Showing the first eight; more decompositions exist.

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 139,864 and was likely granted around 1872.

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

Position in π

The digit sequence 139864 first appears in π at position 787,335 of the decimal expansion (the 787,335ordinal-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.
