Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620704, here are decompositions:

  • 43 + 31620661 = 31620704
  • 103 + 31620601 = 31620704
  • 127 + 31620577 = 31620704
  • 223 + 31620481 = 31620704
  • 307 + 31620397 = 31620704
  • 691 + 31620013 = 31620704
  • 751 + 31619953 = 31620704
  • 883 + 31619821 = 31620704

Showing the first eight; more decompositions exist.
