Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561360, here are decompositions:

  • 13 + 561347 = 561360
  • 17 + 561343 = 561360
  • 47 + 561313 = 561360
  • 53 + 561307 = 561360
  • 83 + 561277 = 561360
  • 109 + 561251 = 561360
  • 131 + 561229 = 561360
  • 179 + 561181 = 561360

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 561,360 and was likely granted around 1895.

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