Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163208, here are decompositions:

  • 37 + 163171 = 163208
  • 61 + 163147 = 163208
  • 79 + 163129 = 163208
  • 181 + 163027 = 163208
  • 211 + 162997 = 163208
  • 271 + 162937 = 163208
  • 307 + 162901 = 163208
  • 349 + 162859 = 163208

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 163,208 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 163208 first appears in π at position 9,192 of the decimal expansion (the 9,192ordinal-suffix:nd 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.
