Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624702, here are decompositions:

  • 3 + 31624699 = 31624702
  • 29 + 31624673 = 31624702
  • 41 + 31624661 = 31624702
  • 59 + 31624643 = 31624702
  • 71 + 31624631 = 31624702
  • 89 + 31624613 = 31624702
  • 191 + 31624511 = 31624702
  • 353 + 31624349 = 31624702

Showing the first eight; more decompositions exist.
