Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494498, here are decompositions:

19 + 31494479 = 31494498
29 + 31494469 = 31494498
31 + 31494467 = 31494498
59 + 31494439 = 31494498
67 + 31494431 = 31494498
71 + 31494427 = 31494498
97 + 31494401 = 31494498
109 + 31494389 = 31494498

Showing the first eight; more decompositions exist.
