Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543748, here are decompositions:

  • 37 + 31543711 = 31543748
  • 79 + 31543669 = 31543748
  • 541 + 31543207 = 31543748
  • 739 + 31543009 = 31543748
  • 757 + 31542991 = 31543748
  • 811 + 31542937 = 31543748
  • 919 + 31542829 = 31543748
  • 937 + 31542811 = 31543748

Showing the first eight; more decompositions exist.
