Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171836, here are decompositions:

  • 13 + 171823 = 171836
  • 37 + 171799 = 171836
  • 43 + 171793 = 171836
  • 73 + 171763 = 171836
  • 79 + 171757 = 171836
  • 103 + 171733 = 171836
  • 139 + 171697 = 171836
  • 157 + 171679 = 171836

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 171,836 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 171836 first appears in π at position 73,022 of the decimal expansion (the 73,022ordinal-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.
