Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454058, here are decompositions:

5 + 31454053 = 31454058
61 + 31453997 = 31454058
67 + 31453991 = 31454058
89 + 31453969 = 31454058
101 + 31453957 = 31454058
127 + 31453931 = 31454058
149 + 31453909 = 31454058
179 + 31453879 = 31454058

Showing the first eight; more decompositions exist.
