Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494276, here are decompositions:

13 + 31494263 = 31494276
19 + 31494257 = 31494276
29 + 31494247 = 31494276
97 + 31494179 = 31494276
157 + 31494119 = 31494276
179 + 31494097 = 31494276
193 + 31494083 = 31494276
197 + 31494079 = 31494276

Showing the first eight; more decompositions exist.
