Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507820, here are decompositions:

  • 11 + 507809 = 507820
  • 17 + 507803 = 507820
  • 23 + 507797 = 507820
  • 41 + 507779 = 507820
  • 101 + 507719 = 507820
  • 107 + 507713 = 507820
  • 179 + 507641 = 507820
  • 227 + 507593 = 507820

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 507,820 and was likely granted around 1893.

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