Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499786, here are decompositions:

59 + 2147499727 = 2147499786
79 + 2147499707 = 2147499786
83 + 2147499703 = 2147499786
239 + 2147499547 = 2147499786
277 + 2147499509 = 2147499786
307 + 2147499479 = 2147499786
349 + 2147499437 = 2147499786
353 + 2147499433 = 2147499786

Showing the first eight; more decompositions exist.
