Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165650, here are decompositions:

  • 61 + 165589 = 165650
  • 97 + 165553 = 165650
  • 109 + 165541 = 165650
  • 127 + 165523 = 165650
  • 139 + 165511 = 165650
  • 181 + 165469 = 165650
  • 193 + 165457 = 165650
  • 271 + 165379 = 165650

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 165,650 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 165650 first appears in π at position 512,814 of the decimal expansion (the 512,814ordinal-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.
