Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173566, here are decompositions:

  • 5 + 173561 = 173566
  • 17 + 173549 = 173566
  • 23 + 173543 = 173566
  • 83 + 173483 = 173566
  • 137 + 173429 = 173566
  • 257 + 173309 = 173566
  • 269 + 173297 = 173566
  • 293 + 173273 = 173566

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 173,566 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 173566 first appears in π at position 660,396 of the decimal expansion (the 660,396ordinal-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.
