Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472988, here are decompositions:

29 + 2147472959 = 2147472988
71 + 2147472917 = 2147472988
191 + 2147472797 = 2147472988
431 + 2147472557 = 2147472988
677 + 2147472311 = 2147472988
827 + 2147472161 = 2147472988
887 + 2147472101 = 2147472988
1049 + 2147471939 = 2147472988

Showing the first eight; more decompositions exist.
