Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625754, here are decompositions:

  • 23 + 31625731 = 31625754
  • 31 + 31625723 = 31625754
  • 73 + 31625681 = 31625754
  • 101 + 31625653 = 31625754
  • 103 + 31625651 = 31625754
  • 107 + 31625647 = 31625754
  • 137 + 31625617 = 31625754
  • 151 + 31625603 = 31625754

Showing the first eight; more decompositions exist.
