Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485090, here are decompositions:

11 + 2147485079 = 2147485090
17 + 2147485073 = 2147485090
239 + 2147484851 = 2147485090
269 + 2147484821 = 2147485090
449 + 2147484641 = 2147485090
479 + 2147484611 = 2147485090
521 + 2147484569 = 2147485090
563 + 2147484527 = 2147485090

Showing the first eight; more decompositions exist.
