Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492878, here are decompositions:

  • 7 + 492871 = 492878
  • 79 + 492799 = 492878
  • 97 + 492781 = 492878
  • 109 + 492769 = 492878
  • 157 + 492721 = 492878
  • 277 + 492601 = 492878
  • 367 + 492511 = 492878
  • 457 + 492421 = 492878

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 492,878 and was likely granted around 1893.

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