Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140740, here are decompositions:

  • 11 + 140729 = 140740
  • 23 + 140717 = 140740
  • 59 + 140681 = 140740
  • 101 + 140639 = 140740
  • 113 + 140627 = 140740
  • 137 + 140603 = 140740
  • 191 + 140549 = 140740
  • 263 + 140477 = 140740

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 140,740 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 140740 first appears in π at position 168,366 of the decimal expansion (the 168,366ordinal-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.
