Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469958, here are decompositions:

  • 41 + 2147469917 = 2147469958
  • 467 + 2147469491 = 2147469958
  • 509 + 2147469449 = 2147469958
  • 719 + 2147469239 = 2147469958
  • 827 + 2147469131 = 2147469958
  • 857 + 2147469101 = 2147469958
  • 911 + 2147469047 = 2147469958
  • 941 + 2147469017 = 2147469958

Showing the first eight; more decompositions exist.
