Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468646, here are decompositions:

  • 7 + 2147468639 = 2147468646
  • 47 + 2147468599 = 2147468646
  • 83 + 2147468563 = 2147468646
  • 109 + 2147468537 = 2147468646
  • 139 + 2147468507 = 2147468646
  • 149 + 2147468497 = 2147468646
  • 223 + 2147468423 = 2147468646
  • 229 + 2147468417 = 2147468646

Showing the first eight; more decompositions exist.
