Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454154, here are decompositions:

5 + 31454149 = 31454154
7 + 31454147 = 31454154
31 + 31454123 = 31454154
37 + 31454117 = 31454154
71 + 31454083 = 31454154
73 + 31454081 = 31454154
101 + 31454053 = 31454154
131 + 31454023 = 31454154

Showing the first eight; more decompositions exist.
