Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458756, here are decompositions:

  • 37 + 31458719 = 31458756
  • 47 + 31458709 = 31458756
  • 53 + 31458703 = 31458756
  • 59 + 31458697 = 31458756
  • 67 + 31458689 = 31458756
  • 89 + 31458667 = 31458756
  • 113 + 31458643 = 31458756
  • 149 + 31458607 = 31458756

Showing the first eight; more decompositions exist.
