Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494516, here are decompositions:

7 + 31494509 = 31494516
13 + 31494503 = 31494516
19 + 31494497 = 31494516
37 + 31494479 = 31494516
47 + 31494469 = 31494516
73 + 31494443 = 31494516
89 + 31494427 = 31494516
127 + 31494389 = 31494516

Showing the first eight; more decompositions exist.
