Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165354, here are decompositions:

  • 5 + 165349 = 165354
  • 11 + 165343 = 165354
  • 23 + 165331 = 165354
  • 37 + 165317 = 165354
  • 41 + 165313 = 165354
  • 43 + 165311 = 165354
  • 61 + 165293 = 165354
  • 67 + 165287 = 165354

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 165,354 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 165354 first appears in π at position 205,381 of the decimal expansion (the 205,381ordinal-suffix:st 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.
