Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165930, here are decompositions:

  • 29 + 165901 = 165930
  • 43 + 165887 = 165930
  • 47 + 165883 = 165930
  • 53 + 165877 = 165930
  • 73 + 165857 = 165930
  • 97 + 165833 = 165930
  • 101 + 165829 = 165930
  • 113 + 165817 = 165930

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 165,930 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 165930 first appears in π at position 224,156 of the decimal expansion (the 224,156ordinal-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.
