Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557478, here are decompositions:

  • 17 + 557461 = 557478
  • 29 + 557449 = 557478
  • 101 + 557377 = 557478
  • 107 + 557371 = 557478
  • 109 + 557369 = 557478
  • 139 + 557339 = 557478
  • 149 + 557329 = 557478
  • 157 + 557321 = 557478

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 557,478 and was likely granted around 1895.

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