Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623662, here are decompositions:

  • 73 + 31623589 = 31623662
  • 139 + 31623523 = 31623662
  • 151 + 31623511 = 31623662
  • 163 + 31623499 = 31623662
  • 181 + 31623481 = 31623662
  • 223 + 31623439 = 31623662
  • 241 + 31623421 = 31623662
  • 439 + 31623223 = 31623662

Showing the first eight; more decompositions exist.
