Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463552, here are decompositions:

19 + 31463533 = 31463552
163 + 31463389 = 31463552
199 + 31463353 = 31463552
223 + 31463329 = 31463552
271 + 31463281 = 31463552
283 + 31463269 = 31463552
349 + 31463203 = 31463552
619 + 31462933 = 31463552

Showing the first eight; more decompositions exist.
