Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454274, here are decompositions:

11 + 31454263 = 31454274
53 + 31454221 = 31454274
73 + 31454201 = 31454274
83 + 31454191 = 31454274
113 + 31454161 = 31454274
127 + 31454147 = 31454274
151 + 31454123 = 31454274
157 + 31454117 = 31454274

Showing the first eight; more decompositions exist.
