Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494594, here are decompositions:

11 + 31494583 = 31494594
13 + 31494581 = 31494594
41 + 31494553 = 31494594
97 + 31494497 = 31494594
127 + 31494467 = 31494594
151 + 31494443 = 31494594
163 + 31494431 = 31494594
167 + 31494427 = 31494594

Showing the first eight; more decompositions exist.
