Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494646, here are decompositions:

3 + 31494643 = 31494646
137 + 31494509 = 31494646
149 + 31494497 = 31494646
167 + 31494479 = 31494646
179 + 31494467 = 31494646
257 + 31494389 = 31494646
353 + 31494293 = 31494646
383 + 31494263 = 31494646

Showing the first eight; more decompositions exist.
