Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468892, here are decompositions:

  • 5 + 2147468887 = 2147468892
  • 11 + 2147468881 = 2147468892
  • 31 + 2147468861 = 2147468892
  • 59 + 2147468833 = 2147468892
  • 83 + 2147468809 = 2147468892
  • 89 + 2147468803 = 2147468892
  • 109 + 2147468783 = 2147468892
  • 113 + 2147468779 = 2147468892

Showing the first eight; more decompositions exist.
