Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163390, here are decompositions:

  • 23 + 163367 = 163390
  • 53 + 163337 = 163390
  • 83 + 163307 = 163390
  • 131 + 163259 = 163390
  • 167 + 163223 = 163390
  • 179 + 163211 = 163390
  • 191 + 163199 = 163390
  • 197 + 163193 = 163390

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 163,390 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 163390 first appears in π at position 319,342 of the decimal expansion (the 319,342ordinal-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.
