Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494474, here are decompositions:

5 + 31494469 = 31494474
7 + 31494467 = 31494474
31 + 31494443 = 31494474
43 + 31494431 = 31494474
47 + 31494427 = 31494474
73 + 31494401 = 31494474
127 + 31494347 = 31494474
173 + 31494301 = 31494474

Showing the first eight; more decompositions exist.
