Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449422, here are decompositions:

  • 13 + 31449409 = 31449422
  • 19 + 31449403 = 31449422
  • 61 + 31449361 = 31449422
  • 163 + 31449259 = 31449422
  • 181 + 31449241 = 31449422
  • 379 + 31449043 = 31449422
  • 523 + 31448899 = 31449422
  • 601 + 31448821 = 31449422

Showing the first eight; more decompositions exist.
