Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468858, here are decompositions:

  • 79 + 2147468779 = 2147468858
  • 541 + 2147468317 = 2147468858
  • 727 + 2147468131 = 2147468858
  • 739 + 2147468119 = 2147468858
  • 937 + 2147467921 = 2147468858
  • 1231 + 2147467627 = 2147468858
  • 1279 + 2147467579 = 2147468858
  • 1531 + 2147467327 = 2147468858

Showing the first eight; more decompositions exist.
