Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453494, here are decompositions:

11 + 31453483 = 31453494
31 + 31453463 = 31453494
47 + 31453447 = 31453494
67 + 31453427 = 31453494
73 + 31453421 = 31453494
101 + 31453393 = 31453494
103 + 31453391 = 31453494
173 + 31453321 = 31453494

Showing the first eight; more decompositions exist.
