Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521010, here are decompositions:

  • 29 + 520981 = 521010
  • 41 + 520969 = 521010
  • 43 + 520967 = 521010
  • 47 + 520963 = 521010
  • 53 + 520957 = 521010
  • 67 + 520943 = 521010
  • 89 + 520921 = 521010
  • 97 + 520913 = 521010

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 521,010 and was likely granted around 1894.

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