Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489768, here are decompositions:

  • 181 + 2147489587 = 2147489768
  • 331 + 2147489437 = 2147489768
  • 367 + 2147489401 = 2147489768
  • 421 + 2147489347 = 2147489768
  • 691 + 2147489077 = 2147489768
  • 709 + 2147489059 = 2147489768
  • 751 + 2147489017 = 2147489768
  • 1489 + 2147488279 = 2147489768

Showing the first eight; more decompositions exist.
