Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147428324, here are decompositions:

  • 17 + 2147428307 = 2147428324
  • 47 + 2147428277 = 2147428324
  • 131 + 2147428193 = 2147428324
  • 401 + 2147427923 = 2147428324
  • 647 + 2147427677 = 2147428324
  • 677 + 2147427647 = 2147428324
  • 761 + 2147427563 = 2147428324
  • 773 + 2147427551 = 2147428324

Showing the first eight; more decompositions exist.
