Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622028, here are decompositions:

  • 47 + 31621981 = 31622028
  • 71 + 31621957 = 31622028
  • 79 + 31621949 = 31622028
  • 127 + 31621901 = 31622028
  • 131 + 31621897 = 31622028
  • 149 + 31621879 = 31622028
  • 181 + 31621847 = 31622028
  • 197 + 31621831 = 31622028

Showing the first eight; more decompositions exist.
