Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173122, here are decompositions:

  • 23 + 173099 = 173122
  • 41 + 173081 = 173122
  • 83 + 173039 = 173122
  • 101 + 173021 = 173122
  • 149 + 172973 = 173122
  • 239 + 172883 = 173122
  • 251 + 172871 = 173122
  • 263 + 172859 = 173122

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 173,122 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 173122 first appears in π at position 603,842 of the decimal expansion (the 603,842ordinal-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.
