Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975920, here are decompositions:

  • 13 + 4294975907 = 4294975920
  • 29 + 4294975891 = 4294975920
  • 31 + 4294975889 = 4294975920
  • 43 + 4294975877 = 4294975920
  • 71 + 4294975849 = 4294975920
  • 73 + 4294975847 = 4294975920
  • 127 + 4294975793 = 4294975920
  • 139 + 4294975781 = 4294975920

Showing the first eight; more decompositions exist.
