Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169966, here are decompositions:

  • 23 + 169943 = 169966
  • 29 + 169937 = 169966
  • 47 + 169919 = 169966
  • 53 + 169913 = 169966
  • 107 + 169859 = 169966
  • 149 + 169817 = 169966
  • 197 + 169769 = 169966
  • 233 + 169733 = 169966

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 169,966 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 169966 first appears in π at position 408,441 of the decimal expansion (the 408,441ordinal-suffix:st 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.
