Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151922, here are decompositions:

  • 13 + 151909 = 151922
  • 19 + 151903 = 151922
  • 73 + 151849 = 151922
  • 109 + 151813 = 151922
  • 139 + 151783 = 151922
  • 151 + 151771 = 151922
  • 193 + 151729 = 151922
  • 229 + 151693 = 151922

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 151,922 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 151922 first appears in π at position 450,563 of the decimal expansion (the 450,563ordinal-suffix:rd 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.
