Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463274, here are decompositions:

5 + 31463269 = 31463274
13 + 31463261 = 31463274
47 + 31463227 = 31463274
61 + 31463213 = 31463274
71 + 31463203 = 31463274
107 + 31463167 = 31463274
113 + 31463161 = 31463274
127 + 31463147 = 31463274

Showing the first eight; more decompositions exist.
