Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472622, here are decompositions:

5 + 2147472617 = 2147472622
11 + 2147472611 = 2147472622
131 + 2147472491 = 2147472622
173 + 2147472449 = 2147472622
179 + 2147472443 = 2147472622
311 + 2147472311 = 2147472622
359 + 2147472263 = 2147472622
401 + 2147472221 = 2147472622

Showing the first eight; more decompositions exist.
