Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552894, here are decompositions:

  • 3 + 31552891 = 31552894
  • 11 + 31552883 = 31552894
  • 41 + 31552853 = 31552894
  • 47 + 31552847 = 31552894
  • 167 + 31552727 = 31552894
  • 173 + 31552721 = 31552894
  • 251 + 31552643 = 31552894
  • 491 + 31552403 = 31552894

Showing the first eight; more decompositions exist.
