Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525000, here are decompositions:

  • 17 + 524983 = 525000
  • 19 + 524981 = 525000
  • 29 + 524971 = 525000
  • 31 + 524969 = 525000
  • 37 + 524963 = 525000
  • 41 + 524959 = 525000
  • 43 + 524957 = 525000
  • 53 + 524947 = 525000

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 525,000 and was likely granted around 1894.

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