Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468888, here are decompositions:

  • 7 + 2147468881 = 2147468888
  • 79 + 2147468809 = 2147468888
  • 109 + 2147468779 = 2147468888
  • 457 + 2147468431 = 2147468888
  • 547 + 2147468341 = 2147468888
  • 571 + 2147468317 = 2147468888
  • 619 + 2147468269 = 2147468888
  • 757 + 2147468131 = 2147468888

Showing the first eight; more decompositions exist.
