Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453224, here are decompositions:

17 + 31453207 = 31453224
31 + 31453193 = 31453224
43 + 31453181 = 31453224
53 + 31453171 = 31453224
67 + 31453157 = 31453224
83 + 31453141 = 31453224
251 + 31452973 = 31453224
281 + 31452943 = 31453224

Showing the first eight; more decompositions exist.
