Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499776, here are decompositions:

  • 73 + 2147499703 = 2147499776
  • 199 + 2147499577 = 2147499776
  • 229 + 2147499547 = 2147499776
  • 397 + 2147499379 = 2147499776
  • 523 + 2147499253 = 2147499776
  • 739 + 2147499037 = 2147499776
  • 823 + 2147498953 = 2147499776
  • 859 + 2147498917 = 2147499776

Showing the first eight; more decompositions exist.
