Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163288, here are decompositions:

  • 29 + 163259 = 163288
  • 89 + 163199 = 163288
  • 107 + 163181 = 163288
  • 137 + 163151 = 163288
  • 179 + 163109 = 163288
  • 227 + 163061 = 163288
  • 269 + 163019 = 163288
  • 317 + 162971 = 163288

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 163,288 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 163288 first appears in π at position 835,738 of the decimal expansion (the 835,738ordinal-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.
