Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164286, here are decompositions:

  • 7 + 164279 = 164286
  • 19 + 164267 = 164286
  • 37 + 164249 = 164286
  • 47 + 164239 = 164286
  • 53 + 164233 = 164286
  • 103 + 164183 = 164286
  • 113 + 164173 = 164286
  • 137 + 164149 = 164286

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 164,286 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 164286 first appears in π at position 693,855 of the decimal expansion (the 693,855ordinal-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.
