Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499782, here are decompositions:

  • 79 + 2147499703 = 2147499782
  • 271 + 2147499511 = 2147499782
  • 331 + 2147499451 = 2147499782
  • 349 + 2147499433 = 2147499782
  • 433 + 2147499349 = 2147499782
  • 499 + 2147499283 = 2147499782
  • 541 + 2147499241 = 2147499782
  • 643 + 2147499139 = 2147499782

Showing the first eight; more decompositions exist.
