Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489940, here are decompositions:

23 + 2147489917 = 2147489940
31 + 2147489909 = 2147489940
41 + 2147489899 = 2147489940
67 + 2147489873 = 2147489940
97 + 2147489843 = 2147489940
223 + 2147489717 = 2147489940
227 + 2147489713 = 2147489940
241 + 2147489699 = 2147489940

Showing the first eight; more decompositions exist.
