Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170812, here are decompositions:

  • 3 + 170809 = 170812
  • 11 + 170801 = 170812
  • 53 + 170759 = 170812
  • 71 + 170741 = 170812
  • 101 + 170711 = 170812
  • 179 + 170633 = 170812
  • 233 + 170579 = 170812
  • 419 + 170393 = 170812

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 170,812 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
