Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468812, here are decompositions:

  • 3 + 2147468809 = 2147468812
  • 11 + 2147468801 = 2147468812
  • 29 + 2147468783 = 2147468812
  • 59 + 2147468753 = 2147468812
  • 173 + 2147468639 = 2147468812
  • 191 + 2147468621 = 2147468812
  • 383 + 2147468429 = 2147468812
  • 389 + 2147468423 = 2147468812

Showing the first eight; more decompositions exist.
