Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623632, here are decompositions:

  • 43 + 31623589 = 31623632
  • 109 + 31623523 = 31623632
  • 151 + 31623481 = 31623632
  • 193 + 31623439 = 31623632
  • 211 + 31623421 = 31623632
  • 409 + 31623223 = 31623632
  • 421 + 31623211 = 31623632
  • 433 + 31623199 = 31623632

Showing the first eight; more decompositions exist.
