Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549920, here are decompositions:

  • 37 + 549883 = 549920
  • 43 + 549877 = 549920
  • 103 + 549817 = 549920
  • 181 + 549739 = 549920
  • 229 + 549691 = 549920
  • 271 + 549649 = 549920
  • 277 + 549643 = 549920
  • 313 + 549607 = 549920

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 549,920 and was likely granted around 1895.

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