Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31678, here are decompositions:

11 + 31667 = 31678
29 + 31649 = 31678
71 + 31607 = 31678
131 + 31547 = 31678
137 + 31541 = 31678
167 + 31511 = 31678
197 + 31481 = 31678
281 + 31397 = 31678

Showing the first eight; more decompositions exist.
