Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167778, here are decompositions:

  • 7 + 167771 = 167778
  • 19 + 167759 = 167778
  • 31 + 167747 = 167778
  • 67 + 167711 = 167778
  • 101 + 167677 = 167778
  • 137 + 167641 = 167778
  • 151 + 167627 = 167778
  • 157 + 167621 = 167778

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 167,778 and was likely granted around 1874.

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