Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169156, here are decompositions:

  • 5 + 169151 = 169156
  • 59 + 169097 = 169156
  • 89 + 169067 = 169156
  • 107 + 169049 = 169156
  • 137 + 169019 = 169156
  • 149 + 169007 = 169156
  • 179 + 168977 = 169156
  • 257 + 168899 = 169156

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 169,156 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 169156 first appears in π at position 929,557 of the decimal expansion (the 929,557ordinal-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.
