Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483784, here are decompositions:

  • 7 + 2147483777 = 2147483784
  • 41 + 2147483743 = 2147483784
  • 71 + 2147483713 = 2147483784
  • 137 + 2147483647 = 2147483784
  • 197 + 2147483587 = 2147483784
  • 241 + 2147483543 = 2147483784
  • 307 + 2147483477 = 2147483784
  • 431 + 2147483353 = 2147483784

Showing the first eight; more decompositions exist.
