Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505158, here are decompositions:

  • 19 + 505139 = 505158
  • 29 + 505129 = 505158
  • 41 + 505117 = 505158
  • 47 + 505111 = 505158
  • 61 + 505097 = 505158
  • 67 + 505091 = 505158
  • 97 + 505061 = 505158
  • 107 + 505051 = 505158

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 505,158 and was likely granted around 1893.

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