Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469518, here are decompositions:

  • 97 + 2147469421 = 2147469518
  • 331 + 2147469187 = 2147469518
  • 547 + 2147468971 = 2147469518
  • 631 + 2147468887 = 2147469518
  • 709 + 2147468809 = 2147469518
  • 739 + 2147468779 = 2147469518
  • 919 + 2147468599 = 2147469518
  • 1021 + 2147468497 = 2147469518

Showing the first eight; more decompositions exist.
