Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468566, here are decompositions:

  • 3 + 2147468563 = 2147468566
  • 29 + 2147468537 = 2147468566
  • 59 + 2147468507 = 2147468566
  • 137 + 2147468429 = 2147468566
  • 149 + 2147468417 = 2147468566
  • 317 + 2147468249 = 2147468566
  • 563 + 2147468003 = 2147468566
  • 599 + 2147467967 = 2147468566

Showing the first eight; more decompositions exist.
