Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621114, here are decompositions:

  • 17 + 31621097 = 31621114
  • 71 + 31621043 = 31621114
  • 101 + 31621013 = 31621114
  • 113 + 31621001 = 31621114
  • 167 + 31620947 = 31621114
  • 293 + 31620821 = 31621114
  • 431 + 31620683 = 31621114
  • 593 + 31620521 = 31621114

Showing the first eight; more decompositions exist.
