Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140742, here are decompositions:

  • 11 + 140731 = 140742
  • 13 + 140729 = 140742
  • 53 + 140689 = 140742
  • 59 + 140683 = 140742
  • 61 + 140681 = 140742
  • 79 + 140663 = 140742
  • 83 + 140659 = 140742
  • 103 + 140639 = 140742

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 140,742 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 140742 first appears in π at position 611,337 of the decimal expansion (the 611,337ordinal-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.
