Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463268, here are decompositions:

7 + 31463261 = 31463268
19 + 31463249 = 31463268
41 + 31463227 = 31463268
71 + 31463197 = 31463268
101 + 31463167 = 31463268
107 + 31463161 = 31463268
131 + 31463137 = 31463268
181 + 31463087 = 31463268

Showing the first eight; more decompositions exist.
