Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550128, here are decompositions:

  • 11 + 550117 = 550128
  • 17 + 550111 = 550128
  • 67 + 550061 = 550128
  • 79 + 550049 = 550128
  • 101 + 550027 = 550128
  • 149 + 549979 = 550128
  • 151 + 549977 = 550128
  • 179 + 549949 = 550128

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 550,128 and was likely granted around 1895.

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