Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525528, here are decompositions:

  • 11 + 525517 = 525528
  • 37 + 525491 = 525528
  • 61 + 525467 = 525528
  • 67 + 525461 = 525528
  • 71 + 525457 = 525528
  • 89 + 525439 = 525528
  • 97 + 525431 = 525528
  • 131 + 525397 = 525528

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 525,528 and was likely granted around 1894.

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