Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522018, here are decompositions:

  • 19 + 521999 = 522018
  • 37 + 521981 = 522018
  • 89 + 521929 = 522018
  • 131 + 521887 = 522018
  • 137 + 521881 = 522018
  • 139 + 521879 = 522018
  • 149 + 521869 = 522018
  • 157 + 521861 = 522018

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 522,018 and was likely granted around 1894.

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