Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499784, here are decompositions:

  • 113 + 2147499671 = 2147499784
  • 167 + 2147499617 = 2147499784
  • 251 + 2147499533 = 2147499784
  • 263 + 2147499521 = 2147499784
  • 347 + 2147499437 = 2147499784
  • 383 + 2147499401 = 2147499784
  • 461 + 2147499323 = 2147499784
  • 491 + 2147499293 = 2147499784

Showing the first eight; more decompositions exist.
