Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623756, here are decompositions:

  • 53 + 31623703 = 31623756
  • 89 + 31623667 = 31623756
  • 139 + 31623617 = 31623756
  • 149 + 31623607 = 31623756
  • 167 + 31623589 = 31623756
  • 233 + 31623523 = 31623756
  • 257 + 31623499 = 31623756
  • 277 + 31623479 = 31623756

Showing the first eight; more decompositions exist.
