Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549090, here are decompositions:

  • 19 + 549071 = 549090
  • 53 + 549037 = 549090
  • 67 + 549023 = 549090
  • 71 + 549019 = 549090
  • 79 + 549011 = 549090
  • 89 + 549001 = 549090
  • 127 + 548963 = 549090
  • 137 + 548953 = 549090

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 549,090 and was likely granted around 1895.

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