Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162186, here are decompositions:

  • 43 + 162143 = 162186
  • 67 + 162119 = 162186
  • 107 + 162079 = 162186
  • 127 + 162059 = 162186
  • 179 + 162007 = 162186
  • 229 + 161957 = 162186
  • 239 + 161947 = 162186
  • 263 + 161923 = 162186

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 162,186 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 162186 first appears in π at position 817,123 of the decimal expansion (the 817,123ordinal-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.
