Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626052, here are decompositions:

  • 11 + 31626041 = 31626052
  • 41 + 31626011 = 31626052
  • 71 + 31625981 = 31626052
  • 83 + 31625969 = 31626052
  • 89 + 31625963 = 31626052
  • 113 + 31625939 = 31626052
  • 233 + 31625819 = 31626052
  • 401 + 31625651 = 31626052

Showing the first eight; more decompositions exist.
