Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463330, here are decompositions:

13 + 31463317 = 31463330
61 + 31463269 = 31463330
103 + 31463227 = 31463330
127 + 31463203 = 31463330
163 + 31463167 = 31463330
193 + 31463137 = 31463330
307 + 31463023 = 31463330
397 + 31462933 = 31463330

Showing the first eight; more decompositions exist.
