Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530128, here are decompositions:

  • 41 + 530087 = 530128
  • 101 + 530027 = 530128
  • 107 + 530021 = 530128
  • 149 + 529979 = 530128
  • 167 + 529961 = 530128
  • 257 + 529871 = 530128
  • 281 + 529847 = 530128
  • 317 + 529811 = 530128

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 530,128 and was likely granted around 1894.

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