Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486942, here are decompositions:

151 + 2147486791 = 2147486942
193 + 2147486749 = 2147486942
613 + 2147486329 = 2147486942
631 + 2147486311 = 2147486942
673 + 2147486269 = 2147486942
739 + 2147486203 = 2147486942
919 + 2147486023 = 2147486942
1123 + 2147485819 = 2147486942

Showing the first eight; more decompositions exist.
