Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515080, here are decompositions:

  • 113 + 514967 = 515080
  • 131 + 514949 = 515080
  • 191 + 514889 = 515080
  • 227 + 514853 = 515080
  • 233 + 514847 = 515080
  • 239 + 514841 = 515080
  • 257 + 514823 = 515080
  • 311 + 514769 = 515080

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 515,080 and was likely granted around 1894.

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