Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549328, here are decompositions:

  • 5 + 549323 = 549328
  • 47 + 549281 = 549328
  • 71 + 549257 = 549328
  • 107 + 549221 = 549328
  • 167 + 549161 = 549328
  • 179 + 549149 = 549328
  • 239 + 549089 = 549328
  • 257 + 549071 = 549328

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 549,328 and was likely granted around 1895.

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