Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172756, here are decompositions:

  • 5 + 172751 = 172756
  • 47 + 172709 = 172756
  • 83 + 172673 = 172756
  • 107 + 172649 = 172756
  • 113 + 172643 = 172756
  • 137 + 172619 = 172756
  • 149 + 172607 = 172756
  • 167 + 172589 = 172756

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 172,756 and was likely granted around 1874.

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

Position in π

The digit sequence 172756 first appears in π at position 76,997 of the decimal expansion (the 76,997ordinal-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.
