Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516324, here are decompositions:

5 + 31516319 = 31516324
71 + 31516253 = 31516324
83 + 31516241 = 31516324
167 + 31516157 = 31516324
263 + 31516061 = 31516324
317 + 31516007 = 31516324
383 + 31515941 = 31516324
431 + 31515893 = 31516324

Showing the first eight; more decompositions exist.
