Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545046, here are decompositions:

  • 23 + 31545023 = 31545046
  • 83 + 31544963 = 31545046
  • 167 + 31544879 = 31545046
  • 227 + 31544819 = 31545046
  • 263 + 31544783 = 31545046
  • 389 + 31544657 = 31545046
  • 503 + 31544543 = 31545046
  • 653 + 31544393 = 31545046

Showing the first eight; more decompositions exist.
