Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463152, here are decompositions:

5 + 31463147 = 31463152
29 + 31463123 = 31463152
53 + 31463099 = 31463152
89 + 31463063 = 31463152
173 + 31462979 = 31463152
251 + 31462901 = 31463152
263 + 31462889 = 31463152
359 + 31462793 = 31463152

Showing the first eight; more decompositions exist.
