Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130556, here are decompositions:

  • 3 + 130553 = 130556
  • 43 + 130513 = 130556
  • 67 + 130489 = 130556
  • 73 + 130483 = 130556
  • 79 + 130477 = 130556
  • 109 + 130447 = 130556
  • 157 + 130399 = 130556
  • 193 + 130363 = 130556

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 130,556 and was likely granted around 1872.

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