Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163222, here are decompositions:

  • 11 + 163211 = 163222
  • 23 + 163199 = 163222
  • 29 + 163193 = 163222
  • 41 + 163181 = 163222
  • 53 + 163169 = 163222
  • 71 + 163151 = 163222
  • 113 + 163109 = 163222
  • 233 + 162989 = 163222

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 163,222 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 163222 first appears in π at position 433,035 of the decimal expansion (the 433,035ordinal-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.
