Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454202, here are decompositions:

5 + 31454197 = 31454202
11 + 31454191 = 31454202
41 + 31454161 = 31454202
53 + 31454149 = 31454202
79 + 31454123 = 31454202
149 + 31454053 = 31454202
179 + 31454023 = 31454202
211 + 31453991 = 31454202

Showing the first eight; more decompositions exist.
