Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154470, here are decompositions:

  • 11 + 154459 = 154470
  • 31 + 154439 = 154470
  • 47 + 154423 = 154470
  • 53 + 154417 = 154470
  • 61 + 154409 = 154470
  • 83 + 154387 = 154470
  • 97 + 154373 = 154470
  • 101 + 154369 = 154470

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 154,470 and was likely granted around 1873.

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