Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526874, here are decompositions:

  • 11 + 31526863 = 31526874
  • 83 + 31526791 = 31526874
  • 97 + 31526777 = 31526874
  • 101 + 31526773 = 31526874
  • 103 + 31526771 = 31526874
  • 151 + 31526723 = 31526874
  • 227 + 31526647 = 31526874
  • 241 + 31526633 = 31526874

Showing the first eight; more decompositions exist.
