Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165536, here are decompositions:

  • 3 + 165533 = 165536
  • 13 + 165523 = 165536
  • 67 + 165469 = 165536
  • 73 + 165463 = 165536
  • 79 + 165457 = 165536
  • 139 + 165397 = 165536
  • 157 + 165379 = 165536
  • 193 + 165343 = 165536

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 165,536 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 165536 first appears in π at position 952,759 of the decimal expansion (the 952,759ordinal-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.
