Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483678, here are decompositions:

19 + 2147483659 = 2147483678
31 + 2147483647 = 2147483678
181 + 2147483497 = 2147483678
409 + 2147483269 = 2147483678
499 + 2147483179 = 2147483678
541 + 2147483137 = 2147483678
601 + 2147483077 = 2147483678
619 + 2147483059 = 2147483678

Showing the first eight; more decompositions exist.
