Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140680, here are decompositions:

  • 3 + 140677 = 140680
  • 17 + 140663 = 140680
  • 41 + 140639 = 140680
  • 53 + 140627 = 140680
  • 131 + 140549 = 140680
  • 227 + 140453 = 140680
  • 257 + 140423 = 140680
  • 263 + 140417 = 140680

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 140,680 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 140680 first appears in π at position 4,194 of the decimal expansion (the 4,194ordinal-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.
