Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169772, here are decompositions:

  • 3 + 169769 = 169772
  • 19 + 169753 = 169772
  • 79 + 169693 = 169772
  • 139 + 169633 = 169772
  • 181 + 169591 = 169772
  • 241 + 169531 = 169772
  • 271 + 169501 = 169772
  • 283 + 169489 = 169772

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 169,772 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 169772 first appears in π at position 381,967 of the decimal expansion (the 381,967ordinal-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.
