Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486892, here are decompositions:

13 + 2147486879 = 2147486892
41 + 2147486851 = 2147486892
43 + 2147486849 = 2147486892
73 + 2147486819 = 2147486892
101 + 2147486791 = 2147486892
151 + 2147486741 = 2147486892
181 + 2147486711 = 2147486892
223 + 2147486669 = 2147486892

Showing the first eight; more decompositions exist.
