Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170908, here are decompositions:

  • 71 + 170837 = 170908
  • 107 + 170801 = 170908
  • 131 + 170777 = 170908
  • 149 + 170759 = 170908
  • 167 + 170741 = 170908
  • 197 + 170711 = 170908
  • 239 + 170669 = 170908
  • 281 + 170627 = 170908

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 170,908 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 170908 first appears in π at position 222,283 of the decimal expansion (the 222,283ordinal-suffix:rd 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.
