Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623602, here are decompositions:

  • 13 + 31623589 = 31623602
  • 79 + 31623523 = 31623602
  • 103 + 31623499 = 31623602
  • 163 + 31623439 = 31623602
  • 181 + 31623421 = 31623602
  • 229 + 31623373 = 31623602
  • 379 + 31623223 = 31623602
  • 421 + 31623181 = 31623602

Showing the first eight; more decompositions exist.
