Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525280, here are decompositions:

  • 23 + 525257 = 525280
  • 59 + 525221 = 525280
  • 71 + 525209 = 525280
  • 89 + 525191 = 525280
  • 113 + 525167 = 525280
  • 137 + 525143 = 525280
  • 179 + 525101 = 525280
  • 251 + 525029 = 525280

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 525,280 and was likely granted around 1894.

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