Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494222, here are decompositions:

43 + 31494179 = 31494222
61 + 31494161 = 31494222
79 + 31494143 = 31494222
103 + 31494119 = 31494222
131 + 31494091 = 31494222
139 + 31494083 = 31494222
181 + 31494041 = 31494222
223 + 31493999 = 31494222

Showing the first eight; more decompositions exist.
