Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492460, here are decompositions:

13 + 2147492447 = 2147492460
31 + 2147492429 = 2147492460
67 + 2147492393 = 2147492460
73 + 2147492387 = 2147492460
89 + 2147492371 = 2147492460
107 + 2147492353 = 2147492460
131 + 2147492329 = 2147492460
163 + 2147492297 = 2147492460

Showing the first eight; more decompositions exist.
