Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501782, here are decompositions:

5 + 2147501777 = 2147501782
113 + 2147501669 = 2147501782
263 + 2147501519 = 2147501782
479 + 2147501303 = 2147501782
509 + 2147501273 = 2147501782
653 + 2147501129 = 2147501782
773 + 2147501009 = 2147501782
911 + 2147500871 = 2147501782

Showing the first eight; more decompositions exist.
