Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168626, here are decompositions:

  • 67 + 168559 = 168626
  • 103 + 168523 = 168626
  • 127 + 168499 = 168626
  • 163 + 168463 = 168626
  • 193 + 168433 = 168626
  • 349 + 168277 = 168626
  • 373 + 168253 = 168626
  • 379 + 168247 = 168626

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 168,626 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 168626 first appears in π at position 512,152 of the decimal expansion (the 512,152ordinal-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.
