Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622970, here are decompositions:

  • 11 + 31622959 = 31622970
  • 19 + 31622951 = 31622970
  • 23 + 31622947 = 31622970
  • 31 + 31622939 = 31622970
  • 37 + 31622933 = 31622970
  • 47 + 31622923 = 31622970
  • 89 + 31622881 = 31622970
  • 107 + 31622863 = 31622970

Showing the first eight; more decompositions exist.
