Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494534, here are decompositions:

31 + 31494503 = 31494534
37 + 31494497 = 31494534
67 + 31494467 = 31494534
103 + 31494431 = 31494534
107 + 31494427 = 31494534
233 + 31494301 = 31494534
241 + 31494293 = 31494534
271 + 31494263 = 31494534

Showing the first eight; more decompositions exist.
