Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494574, here are decompositions:

71 + 31494503 = 31494574
107 + 31494467 = 31494574
131 + 31494443 = 31494574
173 + 31494401 = 31494574
227 + 31494347 = 31494574
281 + 31494293 = 31494574
311 + 31494263 = 31494574
317 + 31494257 = 31494574

Showing the first eight; more decompositions exist.
