Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168356, here are decompositions:

  • 3 + 168353 = 168356
  • 79 + 168277 = 168356
  • 103 + 168253 = 168356
  • 109 + 168247 = 168356
  • 163 + 168193 = 168356
  • 229 + 168127 = 168356
  • 313 + 168043 = 168356
  • 439 + 167917 = 168356

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 168,356 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 168356 first appears in π at position 471,279 of the decimal expansion (the 471,279ordinal-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.
