Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515304, here are decompositions:

  • 11 + 515293 = 515304
  • 67 + 515237 = 515304
  • 71 + 515233 = 515304
  • 73 + 515231 = 515304
  • 113 + 515191 = 515304
  • 131 + 515173 = 515304
  • 151 + 515153 = 515304
  • 193 + 515111 = 515304

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 515,304 and was likely granted around 1894.

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