Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454124, here are decompositions:

7 + 31454117 = 31454124
41 + 31454083 = 31454124
43 + 31454081 = 31454124
47 + 31454077 = 31454124
71 + 31454053 = 31454124
101 + 31454023 = 31454124
127 + 31453997 = 31454124
131 + 31453993 = 31454124

Showing the first eight; more decompositions exist.
