Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151804, here are decompositions:

  • 5 + 151799 = 151804
  • 17 + 151787 = 151804
  • 71 + 151733 = 151804
  • 101 + 151703 = 151804
  • 131 + 151673 = 151804
  • 137 + 151667 = 151804
  • 167 + 151637 = 151804
  • 173 + 151631 = 151804

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 151,804 and was likely granted around 1873.

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