Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516024, here are decompositions:

3 + 31516021 = 31516024
17 + 31516007 = 31516024
83 + 31515941 = 31516024
131 + 31515893 = 31516024
167 + 31515857 = 31516024
257 + 31515767 = 31516024
347 + 31515677 = 31516024
383 + 31515641 = 31516024

Showing the first eight; more decompositions exist.
