Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156718, here are decompositions:

  • 11 + 156707 = 156718
  • 41 + 156677 = 156718
  • 47 + 156671 = 156718
  • 59 + 156659 = 156718
  • 179 + 156539 = 156718
  • 197 + 156521 = 156718
  • 227 + 156491 = 156718
  • 251 + 156467 = 156718

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 156,718 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 156718 first appears in π at position 632,782 of the decimal expansion (the 632,782ordinal-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.
