Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516128, here are decompositions:

  • 37 + 516091 = 516128
  • 79 + 516049 = 516128
  • 199 + 515929 = 516128
  • 211 + 515917 = 516128
  • 241 + 515887 = 516128
  • 271 + 515857 = 516128
  • 367 + 515761 = 516128
  • 541 + 515587 = 516128

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 516,128 and was likely granted around 1894.

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