Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147582988, here are decompositions:

7 + 2147582981 = 2147582988
71 + 2147582917 = 2147582988
127 + 2147582861 = 2147582988
151 + 2147582837 = 2147582988
181 + 2147582807 = 2147582988
367 + 2147582621 = 2147582988
521 + 2147582467 = 2147582988
631 + 2147582357 = 2147582988

Showing the first eight; more decompositions exist.
