Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525380, here are decompositions:

  • 3 + 525377 = 525380
  • 7 + 525373 = 525380
  • 19 + 525361 = 525380
  • 67 + 525313 = 525380
  • 127 + 525253 = 525380
  • 139 + 525241 = 525380
  • 181 + 525199 = 525380
  • 223 + 525157 = 525380

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 525,380 and was likely granted around 1894.

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