Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454150, here are decompositions:

3 + 31454147 = 31454150
67 + 31454083 = 31454150
73 + 31454077 = 31454150
97 + 31454053 = 31454150
127 + 31454023 = 31454150
157 + 31453993 = 31454150
181 + 31453969 = 31454150
193 + 31453957 = 31454150

Showing the first eight; more decompositions exist.
