Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528930, here are decompositions:

  • 19 + 528911 = 528930
  • 47 + 528883 = 528930
  • 53 + 528877 = 528930
  • 67 + 528863 = 528930
  • 97 + 528833 = 528930
  • 107 + 528823 = 528930
  • 109 + 528821 = 528930
  • 131 + 528799 = 528930

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 528,930 and was likely granted around 1894.

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