Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463304, here are decompositions:

23 + 31463281 = 31463304
43 + 31463261 = 31463304
101 + 31463203 = 31463304
107 + 31463197 = 31463304
137 + 31463167 = 31463304
157 + 31463147 = 31463304
167 + 31463137 = 31463304
181 + 31463123 = 31463304

Showing the first eight; more decompositions exist.
