Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139750, here are decompositions:

  • 3 + 139747 = 139750
  • 11 + 139739 = 139750
  • 29 + 139721 = 139750
  • 41 + 139709 = 139750
  • 47 + 139703 = 139750
  • 53 + 139697 = 139750
  • 89 + 139661 = 139750
  • 131 + 139619 = 139750

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 139,750 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 139750 first appears in π at position 539,424 of the decimal expansion (the 539,424ordinal-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.
