Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499440, here are decompositions:

  • 3 + 2147499437 = 2147499440
  • 7 + 2147499433 = 2147499440
  • 61 + 2147499379 = 2147499440
  • 157 + 2147499283 = 2147499440
  • 199 + 2147499241 = 2147499440
  • 223 + 2147499217 = 2147499440
  • 349 + 2147499091 = 2147499440
  • 487 + 2147498953 = 2147499440

Showing the first eight; more decompositions exist.
