Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463256, here are decompositions:

7 + 31463249 = 31463256
29 + 31463227 = 31463256
43 + 31463213 = 31463256
53 + 31463203 = 31463256
59 + 31463197 = 31463256
89 + 31463167 = 31463256
109 + 31463147 = 31463256
157 + 31463099 = 31463256

Showing the first eight; more decompositions exist.
