Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494564, here are decompositions:

11 + 31494553 = 31494564
61 + 31494503 = 31494564
67 + 31494497 = 31494564
97 + 31494467 = 31494564
137 + 31494427 = 31494564
163 + 31494401 = 31494564
263 + 31494301 = 31494564
271 + 31494293 = 31494564

Showing the first eight; more decompositions exist.
