Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163960, here are decompositions:

  • 59 + 163901 = 163960
  • 89 + 163871 = 163960
  • 101 + 163859 = 163960
  • 107 + 163853 = 163960
  • 113 + 163847 = 163960
  • 149 + 163811 = 163960
  • 179 + 163781 = 163960
  • 227 + 163733 = 163960

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 163,960 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 163960 first appears in π at position 697,783 of the decimal expansion (the 697,783ordinal-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.
