Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105966, here are decompositions:

  • 13 + 105953 = 105966
  • 23 + 105943 = 105966
  • 37 + 105929 = 105966
  • 53 + 105913 = 105966
  • 59 + 105907 = 105966
  • 67 + 105899 = 105966
  • 83 + 105883 = 105966
  • 103 + 105863 = 105966

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 105,966 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 105966 first appears in π at position 97,497 of the decimal expansion (the 97,497ordinal-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.
