Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494166, here are decompositions:

5 + 31494161 = 31494166
23 + 31494143 = 31494166
47 + 31494119 = 31494166
83 + 31494083 = 31494166
113 + 31494053 = 31494166
167 + 31493999 = 31494166
239 + 31493927 = 31494166
257 + 31493909 = 31494166

Showing the first eight; more decompositions exist.
