Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517152, here are decompositions:

3 + 31517149 = 31517152
89 + 31517063 = 31517152
113 + 31517039 = 31517152
131 + 31517021 = 31517152
179 + 31516973 = 31517152
263 + 31516889 = 31517152
311 + 31516841 = 31517152
449 + 31516703 = 31517152

Showing the first eight; more decompositions exist.
