Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455134, here are decompositions:

3 + 31455131 = 31455134
13 + 31455121 = 31455134
31 + 31455103 = 31455134
103 + 31455031 = 31455134
163 + 31454971 = 31455134
181 + 31454953 = 31455134
211 + 31454923 = 31455134
307 + 31454827 = 31455134

Showing the first eight; more decompositions exist.
