Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515028, here are decompositions:

  • 61 + 514967 = 515028
  • 79 + 514949 = 515028
  • 89 + 514939 = 515028
  • 139 + 514889 = 515028
  • 181 + 514847 = 515028
  • 197 + 514831 = 515028
  • 271 + 514757 = 515028
  • 277 + 514751 = 515028

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 515,028 and was likely granted around 1894.

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