Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169938, here are decompositions:

  • 5 + 169933 = 169938
  • 19 + 169919 = 169938
  • 29 + 169909 = 169938
  • 47 + 169891 = 169938
  • 79 + 169859 = 169938
  • 101 + 169837 = 169938
  • 107 + 169831 = 169938
  • 149 + 169789 = 169938

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 169,938 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 169938 first appears in π at position 417,265 of the decimal expansion (the 417,265ordinal-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.
