Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167806, here are decompositions:

  • 5 + 167801 = 167806
  • 29 + 167777 = 167806
  • 47 + 167759 = 167806
  • 59 + 167747 = 167806
  • 173 + 167633 = 167806
  • 179 + 167627 = 167806
  • 263 + 167543 = 167806
  • 269 + 167537 = 167806

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 167,806 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 167806 first appears in π at position 703,382 of the decimal expansion (the 703,382ordinal-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.
