Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617324, here are decompositions:

31 + 31617293 = 31617324
41 + 31617283 = 31617324
43 + 31617281 = 31617324
71 + 31617253 = 31617324
73 + 31617251 = 31617324
157 + 31617167 = 31617324
191 + 31617133 = 31617324
223 + 31617101 = 31617324

Showing the first eight; more decompositions exist.
