Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469812, here are decompositions:

  • 31 + 2147469781 = 2147469812
  • 109 + 2147469703 = 2147469812
  • 193 + 2147469619 = 2147469812
  • 349 + 2147469463 = 2147469812
  • 541 + 2147469271 = 2147469812
  • 739 + 2147469073 = 2147469812
  • 811 + 2147469001 = 2147469812
  • 1009 + 2147468803 = 2147469812

Showing the first eight; more decompositions exist.
