Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617906, here are decompositions:

  • 7 + 31617899 = 31617906
  • 17 + 31617889 = 31617906
  • 29 + 31617877 = 31617906
  • 43 + 31617863 = 31617906
  • 53 + 31617853 = 31617906
  • 79 + 31617827 = 31617906
  • 109 + 31617797 = 31617906
  • 149 + 31617757 = 31617906

Showing the first eight; more decompositions exist.
