Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494306, here are decompositions:

5 + 31494301 = 31494306
13 + 31494293 = 31494306
43 + 31494263 = 31494306
59 + 31494247 = 31494306
127 + 31494179 = 31494306
149 + 31494157 = 31494306
163 + 31494143 = 31494306
223 + 31494083 = 31494306

Showing the first eight; more decompositions exist.
