Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140688, here are decompositions:

  • 5 + 140683 = 140688
  • 7 + 140681 = 140688
  • 11 + 140677 = 140688
  • 29 + 140659 = 140688
  • 59 + 140629 = 140688
  • 61 + 140627 = 140688
  • 71 + 140617 = 140688
  • 101 + 140587 = 140688

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 140,688 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 140688 first appears in π at position 488,680 of the decimal expansion (the 488,680ordinal-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.
