Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623832, here are decompositions:

  • 11 + 31623821 = 31623832
  • 101 + 31623731 = 31623832
  • 131 + 31623701 = 31623832
  • 311 + 31623521 = 31623832
  • 353 + 31623479 = 31623832
  • 389 + 31623443 = 31623832
  • 659 + 31623173 = 31623832
  • 719 + 31623113 = 31623832

Showing the first eight; more decompositions exist.
