Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516174, here are decompositions:

17 + 31516157 = 31516174
71 + 31516103 = 31516174
113 + 31516061 = 31516174
167 + 31516007 = 31516174
233 + 31515941 = 31516174
281 + 31515893 = 31516174
293 + 31515881 = 31516174
317 + 31515857 = 31516174

Showing the first eight; more decompositions exist.
