Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975972, here are decompositions:

  • 83 + 4294975889 = 4294975972
  • 179 + 4294975793 = 4294975972
  • 191 + 4294975781 = 4294975972
  • 233 + 4294975739 = 4294975972
  • 239 + 4294975733 = 4294975972
  • 383 + 4294975589 = 4294975972
  • 509 + 4294975463 = 4294975972
  • 743 + 4294975229 = 4294975972

Showing the first eight; more decompositions exist.
