Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491422, here are decompositions:

5 + 2147491417 = 2147491422
19 + 2147491403 = 2147491422
53 + 2147491369 = 2147491422
61 + 2147491361 = 2147491422
73 + 2147491349 = 2147491422
79 + 2147491343 = 2147491422
103 + 2147491319 = 2147491422
149 + 2147491273 = 2147491422

Showing the first eight; more decompositions exist.
