Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453194, here are decompositions:

13 + 31453181 = 31453194
23 + 31453171 = 31453194
37 + 31453157 = 31453194
53 + 31453141 = 31453194
61 + 31453133 = 31453194
173 + 31453021 = 31453194
251 + 31452943 = 31453194
293 + 31452901 = 31453194

Showing the first eight; more decompositions exist.
