Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468454, here are decompositions:

  • 11 + 2147468443 = 2147468454
  • 23 + 2147468431 = 2147468454
  • 31 + 2147468423 = 2147468454
  • 37 + 2147468417 = 2147468454
  • 113 + 2147468341 = 2147468454
  • 137 + 2147468317 = 2147468454
  • 163 + 2147468291 = 2147468454
  • 223 + 2147468231 = 2147468454

Showing the first eight; more decompositions exist.
