Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544944, here are decompositions:

  • 3 + 31544941 = 31544944
  • 173 + 31544771 = 31544944
  • 227 + 31544717 = 31544944
  • 383 + 31544561 = 31544944
  • 401 + 31544543 = 31544944
  • 647 + 31544297 = 31544944
  • 773 + 31544171 = 31544944
  • 887 + 31544057 = 31544944

Showing the first eight; more decompositions exist.
