Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452646, here are decompositions:

  • 23 + 31452623 = 31452646
  • 47 + 31452599 = 31452646
  • 59 + 31452587 = 31452646
  • 107 + 31452539 = 31452646
  • 149 + 31452497 = 31452646
  • 227 + 31452419 = 31452646
  • 443 + 31452203 = 31452646
  • 509 + 31452137 = 31452646

Showing the first eight; more decompositions exist.
