Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491988, here are decompositions:

151 + 2147491837 = 2147491988
157 + 2147491831 = 2147491988
379 + 2147491609 = 2147491988
571 + 2147491417 = 2147491988
619 + 2147491369 = 2147491988
727 + 2147491261 = 2147491988
739 + 2147491249 = 2147491988
751 + 2147491237 = 2147491988

Showing the first eight; more decompositions exist.
