Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522126, here are decompositions:

  • 23 + 31522103 = 31522126
  • 107 + 31522019 = 31522126
  • 113 + 31522013 = 31522126
  • 149 + 31521977 = 31522126
  • 173 + 31521953 = 31522126
  • 239 + 31521887 = 31522126
  • 263 + 31521863 = 31522126
  • 443 + 31521683 = 31522126

Showing the first eight; more decompositions exist.
