Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468924, here are decompositions:

  • 37 + 2147468887 = 2147468924
  • 43 + 2147468881 = 2147468924
  • 151 + 2147468773 = 2147468924
  • 421 + 2147468503 = 2147468924
  • 607 + 2147468317 = 2147468924
  • 691 + 2147468233 = 2147468924
  • 751 + 2147468173 = 2147468924
  • 1123 + 2147467801 = 2147468924

Showing the first eight; more decompositions exist.
