Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486922, here are decompositions:

13 + 2147486909 = 2147486922
43 + 2147486879 = 2147486922
71 + 2147486851 = 2147486922
73 + 2147486849 = 2147486922
79 + 2147486843 = 2147486922
103 + 2147486819 = 2147486922
131 + 2147486791 = 2147486922
173 + 2147486749 = 2147486922

Showing the first eight; more decompositions exist.
