Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492068, here are decompositions:

107 + 2147491961 = 2147492068
131 + 2147491937 = 2147492068
311 + 2147491757 = 2147492068
461 + 2147491607 = 2147492068
509 + 2147491559 = 2147492068
521 + 2147491547 = 2147492068
719 + 2147491349 = 2147492068
929 + 2147491139 = 2147492068

Showing the first eight; more decompositions exist.
