Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494508, here are decompositions:

5 + 31494503 = 31494508
11 + 31494497 = 31494508
29 + 31494479 = 31494508
41 + 31494467 = 31494508
107 + 31494401 = 31494508
251 + 31494257 = 31494508
347 + 31494161 = 31494508
389 + 31494119 = 31494508

Showing the first eight; more decompositions exist.
