Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147788, here are decompositions:

  • 19 + 147769 = 147788
  • 61 + 147727 = 147788
  • 79 + 147709 = 147788
  • 127 + 147661 = 147788
  • 181 + 147607 = 147788
  • 241 + 147547 = 147788
  • 271 + 147517 = 147788
  • 307 + 147481 = 147788

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 147,788 and was likely granted around 1873.

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