Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454646, here are decompositions:

  • 19 + 31454627 = 31454646
  • 59 + 31454587 = 31454646
  • 149 + 31454497 = 31454646
  • 163 + 31454483 = 31454646
  • 257 + 31454389 = 31454646
  • 263 + 31454383 = 31454646
  • 269 + 31454377 = 31454646
  • 383 + 31454263 = 31454646

Showing the first eight; more decompositions exist.
