Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525660, here are decompositions:

  • 11 + 525649 = 525660
  • 19 + 525641 = 525660
  • 53 + 525607 = 525660
  • 61 + 525599 = 525660
  • 67 + 525593 = 525660
  • 89 + 525571 = 525660
  • 127 + 525533 = 525660
  • 131 + 525529 = 525660

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 525,660 and was likely granted around 1894.

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