Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463396, here are decompositions:

7 + 31463389 = 31463396
43 + 31463353 = 31463396
67 + 31463329 = 31463396
79 + 31463317 = 31463396
127 + 31463269 = 31463396
193 + 31463203 = 31463396
199 + 31463197 = 31463396
229 + 31463167 = 31463396

Showing the first eight; more decompositions exist.
