Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463316, here are decompositions:

47 + 31463269 = 31463316
67 + 31463249 = 31463316
89 + 31463227 = 31463316
103 + 31463213 = 31463316
113 + 31463203 = 31463316
149 + 31463167 = 31463316
179 + 31463137 = 31463316
193 + 31463123 = 31463316

Showing the first eight; more decompositions exist.
