Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623608, here are decompositions:

  • 19 + 31623589 = 31623608
  • 97 + 31623511 = 31623608
  • 109 + 31623499 = 31623608
  • 127 + 31623481 = 31623608
  • 271 + 31623337 = 31623608
  • 397 + 31623211 = 31623608
  • 409 + 31623199 = 31623608
  • 439 + 31623169 = 31623608

Showing the first eight; more decompositions exist.
