Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163200, here are decompositions:

  • 7 + 163193 = 163200
  • 19 + 163181 = 163200
  • 29 + 163171 = 163200
  • 31 + 163169 = 163200
  • 53 + 163147 = 163200
  • 71 + 163129 = 163200
  • 73 + 163127 = 163200
  • 83 + 163117 = 163200

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 163,200 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 163200 first appears in π at position 100,037 of the decimal expansion (the 100,037ordinal-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.
