Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483818, here are decompositions:

5 + 2147483813 = 2147483818
41 + 2147483777 = 2147483818
239 + 2147483579 = 2147483818
269 + 2147483549 = 2147483818
419 + 2147483399 = 2147483818
569 + 2147483249 = 2147483818
647 + 2147483171 = 2147483818
881 + 2147482937 = 2147483818

Showing the first eight; more decompositions exist.
