Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494510, here are decompositions:

7 + 31494503 = 31494510
13 + 31494497 = 31494510
31 + 31494479 = 31494510
41 + 31494469 = 31494510
43 + 31494467 = 31494510
67 + 31494443 = 31494510
71 + 31494439 = 31494510
79 + 31494431 = 31494510

Showing the first eight; more decompositions exist.
