Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147399076, here are decompositions:

  • 7 + 2147399069 = 2147399076
  • 13 + 2147399063 = 2147399076
  • 23 + 2147399053 = 2147399076
  • 59 + 2147399017 = 2147399076
  • 79 + 2147398997 = 2147399076
  • 107 + 2147398969 = 2147399076
  • 113 + 2147398963 = 2147399076
  • 127 + 2147398949 = 2147399076

Showing the first eight; more decompositions exist.
