Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494462, here are decompositions:

19 + 31494443 = 31494462
23 + 31494439 = 31494462
31 + 31494431 = 31494462
61 + 31494401 = 31494462
73 + 31494389 = 31494462
199 + 31494263 = 31494462
283 + 31494179 = 31494462
379 + 31494083 = 31494462

Showing the first eight; more decompositions exist.
