Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165204, here are decompositions:

  • 23 + 165181 = 165204
  • 31 + 165173 = 165204
  • 43 + 165161 = 165204
  • 71 + 165133 = 165204
  • 101 + 165103 = 165204
  • 157 + 165047 = 165204
  • 163 + 165041 = 165204
  • 167 + 165037 = 165204

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 165,204 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 165204 first appears in π at position 470,774 of the decimal expansion (the 470,774ordinal-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.
