Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548548, here are decompositions:

  • 439 + 31548109 = 31548548
  • 541 + 31548007 = 31548548
  • 631 + 31547917 = 31548548
  • 709 + 31547839 = 31548548
  • 877 + 31547671 = 31548548
  • 907 + 31547641 = 31548548
  • 919 + 31547629 = 31548548
  • 991 + 31547557 = 31548548

Showing the first eight; more decompositions exist.
