Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452212, here are decompositions:

3 + 31452209 = 31452212
13 + 31452199 = 31452212
31 + 31452181 = 31452212
151 + 31452061 = 31452212
193 + 31452019 = 31452212
199 + 31452013 = 31452212
283 + 31451929 = 31452212
331 + 31451881 = 31452212

Showing the first eight; more decompositions exist.
