Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494162, here are decompositions:

5 + 31494157 = 31494162
19 + 31494143 = 31494162
43 + 31494119 = 31494162
71 + 31494091 = 31494162
79 + 31494083 = 31494162
83 + 31494079 = 31494162
109 + 31494053 = 31494162
163 + 31493999 = 31494162

Showing the first eight; more decompositions exist.
