Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140646, here are decompositions:

  • 7 + 140639 = 140646
  • 17 + 140629 = 140646
  • 19 + 140627 = 140646
  • 29 + 140617 = 140646
  • 43 + 140603 = 140646
  • 53 + 140593 = 140646
  • 59 + 140587 = 140646
  • 89 + 140557 = 140646

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 140,646 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 140646 first appears in π at position 170,142 of the decimal expansion (the 170,142ordinal-suffix:nd 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.
