Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554744, here are decompositions:

  • 5 + 31554739 = 31554744
  • 73 + 31554671 = 31554744
  • 103 + 31554641 = 31554744
  • 107 + 31554637 = 31554744
  • 113 + 31554631 = 31554744
  • 127 + 31554617 = 31554744
  • 131 + 31554613 = 31554744
  • 173 + 31554571 = 31554744

Showing the first eight; more decompositions exist.
