Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494522, here are decompositions:

13 + 31494509 = 31494522
19 + 31494503 = 31494522
43 + 31494479 = 31494522
53 + 31494469 = 31494522
79 + 31494443 = 31494522
83 + 31494439 = 31494522
229 + 31494293 = 31494522
281 + 31494241 = 31494522

Showing the first eight; more decompositions exist.
