Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294989144, here are decompositions:

  • 7 + 4294989137 = 4294989144
  • 31 + 4294989113 = 4294989144
  • 41 + 4294989103 = 4294989144
  • 71 + 4294989073 = 4294989144
  • 163 + 4294988981 = 4294989144
  • 181 + 4294988963 = 4294989144
  • 197 + 4294988947 = 4294989144
  • 241 + 4294988903 = 4294989144

Showing the first eight; more decompositions exist.
