Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31722, here are decompositions:

  • 23 + 31699 = 31722
  • 59 + 31663 = 31722
  • 73 + 31649 = 31722
  • 79 + 31643 = 31722
  • 139 + 31583 = 31722
  • 149 + 31573 = 31722
  • 179 + 31543 = 31722
  • 181 + 31541 = 31722

Showing the first eight; more decompositions exist.
