Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556380, here are decompositions:

  • 7 + 556373 = 556380
  • 29 + 556351 = 556380
  • 37 + 556343 = 556380
  • 53 + 556327 = 556380
  • 59 + 556321 = 556380
  • 67 + 556313 = 556380
  • 101 + 556279 = 556380
  • 107 + 556273 = 556380

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 556,380 and was likely granted around 1895.

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