Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468862, here are decompositions:

  • 29 + 2147468833 = 2147468862
  • 53 + 2147468809 = 2147468862
  • 59 + 2147468803 = 2147468862
  • 61 + 2147468801 = 2147468862
  • 79 + 2147468783 = 2147468862
  • 83 + 2147468779 = 2147468862
  • 89 + 2147468773 = 2147468862
  • 109 + 2147468753 = 2147468862

Showing the first eight; more decompositions exist.
