Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165524, here are decompositions:

  • 13 + 165511 = 165524
  • 61 + 165463 = 165524
  • 67 + 165457 = 165524
  • 127 + 165397 = 165524
  • 157 + 165367 = 165524
  • 181 + 165343 = 165524
  • 193 + 165331 = 165524
  • 211 + 165313 = 165524

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 165,524 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 165524 first appears in π at position 382,402 of the decimal expansion (the 382,402ordinal-suffix:nd 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.
