Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454106, here are decompositions:

23 + 31454083 = 31454106
29 + 31454077 = 31454106
53 + 31454053 = 31454106
83 + 31454023 = 31454106
109 + 31453997 = 31454106
113 + 31453993 = 31454106
137 + 31453969 = 31454106
149 + 31453957 = 31454106

Showing the first eight; more decompositions exist.
