Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497882, here are decompositions:

  • 113 + 2147497769 = 2147497882
  • 149 + 2147497733 = 2147497882
  • 191 + 2147497691 = 2147497882
  • 311 + 2147497571 = 2147497882
  • 359 + 2147497523 = 2147497882
  • 389 + 2147497493 = 2147497882
  • 401 + 2147497481 = 2147497882
  • 479 + 2147497403 = 2147497882

Showing the first eight; more decompositions exist.
