Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165598, here are decompositions:

  • 11 + 165587 = 165598
  • 29 + 165569 = 165598
  • 47 + 165551 = 165598
  • 71 + 165527 = 165598
  • 149 + 165449 = 165598
  • 281 + 165317 = 165598
  • 311 + 165287 = 165598
  • 509 + 165089 = 165598

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 165,598 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 165598 first appears in π at position 110,535 of the decimal expansion (the 110,535ordinal-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.
