Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623446, here are decompositions:

  • 3 + 31623443 = 31623446
  • 7 + 31623439 = 31623446
  • 73 + 31623373 = 31623446
  • 103 + 31623343 = 31623446
  • 109 + 31623337 = 31623446
  • 223 + 31623223 = 31623446
  • 277 + 31623169 = 31623446
  • 487 + 31622959 = 31623446

Showing the first eight; more decompositions exist.
