Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171562, here are decompositions:

  • 3 + 171559 = 171562
  • 23 + 171539 = 171562
  • 71 + 171491 = 171562
  • 89 + 171473 = 171562
  • 113 + 171449 = 171562
  • 179 + 171383 = 171562
  • 233 + 171329 = 171562
  • 263 + 171299 = 171562

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 171,562 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 171562 first appears in π at position 635,345 of the decimal expansion (the 635,345ordinal-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.
