Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463366, here are decompositions:

3 + 31463363 = 31463366
13 + 31463353 = 31463366
37 + 31463329 = 31463366
97 + 31463269 = 31463366
139 + 31463227 = 31463366
163 + 31463203 = 31463366
199 + 31463167 = 31463366
229 + 31463137 = 31463366

Showing the first eight; more decompositions exist.
