Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494484, here are decompositions:

5 + 31494479 = 31494484
17 + 31494467 = 31494484
41 + 31494443 = 31494484
53 + 31494431 = 31494484
83 + 31494401 = 31494484
137 + 31494347 = 31494484
191 + 31494293 = 31494484
227 + 31494257 = 31494484

Showing the first eight; more decompositions exist.
