Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169850, here are decompositions:

  • 7 + 169843 = 169850
  • 13 + 169837 = 169850
  • 19 + 169831 = 169850
  • 61 + 169789 = 169850
  • 67 + 169783 = 169850
  • 73 + 169777 = 169850
  • 97 + 169753 = 169850
  • 157 + 169693 = 169850

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 169,850 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 169850 first appears in π at position 391,943 of the decimal expansion (the 391,943ordinal-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.
