Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491858, here are decompositions:

101 + 2147491757 = 2147491858
167 + 2147491691 = 2147491858
251 + 2147491607 = 2147491858
311 + 2147491547 = 2147491858
509 + 2147491349 = 2147491858
641 + 2147491217 = 2147491858
719 + 2147491139 = 2147491858
797 + 2147491061 = 2147491858

Showing the first eight; more decompositions exist.
