Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494552, here are decompositions:

43 + 31494509 = 31494552
73 + 31494479 = 31494552
83 + 31494469 = 31494552
109 + 31494443 = 31494552
113 + 31494439 = 31494552
151 + 31494401 = 31494552
163 + 31494389 = 31494552
251 + 31494301 = 31494552

Showing the first eight; more decompositions exist.
