Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510542, here are decompositions:

  • 13 + 510529 = 510542
  • 61 + 510481 = 510542
  • 79 + 510463 = 510542
  • 139 + 510403 = 510542
  • 163 + 510379 = 510542
  • 181 + 510361 = 510542
  • 211 + 510331 = 510542
  • 223 + 510319 = 510542

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 510,542 and was likely granted around 1893.

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