Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494228, here are decompositions:

67 + 31494161 = 31494228
71 + 31494157 = 31494228
109 + 31494119 = 31494228
131 + 31494097 = 31494228
137 + 31494091 = 31494228
149 + 31494079 = 31494228
229 + 31493999 = 31494228
239 + 31493989 = 31494228

Showing the first eight; more decompositions exist.
