Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155376, here are decompositions:

  • 5 + 155371 = 155376
  • 43 + 155333 = 155376
  • 59 + 155317 = 155376
  • 73 + 155303 = 155376
  • 107 + 155269 = 155376
  • 157 + 155219 = 155376
  • 167 + 155209 = 155376
  • 173 + 155203 = 155376

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 155,376 and was likely granted around 1873.

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