Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544422, here are decompositions:

  • 5 + 31544417 = 31544422
  • 29 + 31544393 = 31544422
  • 59 + 31544363 = 31544422
  • 233 + 31544189 = 31544422
  • 251 + 31544171 = 31544422
  • 269 + 31544153 = 31544422
  • 383 + 31544039 = 31544422
  • 389 + 31544033 = 31544422

Showing the first eight; more decompositions exist.
