Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155474, here are decompositions:

  • 13 + 155461 = 155474
  • 31 + 155443 = 155474
  • 61 + 155413 = 155474
  • 97 + 155377 = 155474
  • 103 + 155371 = 155474
  • 157 + 155317 = 155474
  • 223 + 155251 = 155474
  • 271 + 155203 = 155474

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 155,474 and was likely granted around 1873.

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