Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494324, here are decompositions:

23 + 31494301 = 31494324
31 + 31494293 = 31494324
61 + 31494263 = 31494324
67 + 31494257 = 31494324
83 + 31494241 = 31494324
163 + 31494161 = 31494324
167 + 31494157 = 31494324
181 + 31494143 = 31494324

Showing the first eight; more decompositions exist.
