Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147549218, here are decompositions:

  • 5 + 2147549213 = 2147549218
  • 29 + 2147549189 = 2147549218
  • 71 + 2147549147 = 2147549218
  • 107 + 2147549111 = 2147549218
  • 389 + 2147548829 = 2147549218
  • 431 + 2147548787 = 2147549218
  • 461 + 2147548757 = 2147549218
  • 467 + 2147548751 = 2147549218

Showing the first eight; more decompositions exist.
