Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147448646, here are decompositions:

  • 17 + 2147448629 = 2147448646
  • 53 + 2147448593 = 2147448646
  • 107 + 2147448539 = 2147448646
  • 173 + 2147448473 = 2147448646
  • 179 + 2147448467 = 2147448646
  • 293 + 2147448353 = 2147448646
  • 359 + 2147448287 = 2147448646
  • 389 + 2147448257 = 2147448646

Showing the first eight; more decompositions exist.
