Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521048, here are decompositions:

  • 7 + 521041 = 521048
  • 67 + 520981 = 521048
  • 79 + 520969 = 521048
  • 127 + 520921 = 521048
  • 181 + 520867 = 521048
  • 211 + 520837 = 521048
  • 331 + 520717 = 521048
  • 349 + 520699 = 521048

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 521,048 and was likely granted around 1894.

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