Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454234, here are decompositions:

13 + 31454221 = 31454234
37 + 31454197 = 31454234
43 + 31454191 = 31454234
73 + 31454161 = 31454234
151 + 31454083 = 31454234
157 + 31454077 = 31454234
181 + 31454053 = 31454234
211 + 31454023 = 31454234

Showing the first eight; more decompositions exist.
