Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454166, here are decompositions:

5 + 31454161 = 31454166
17 + 31454149 = 31454166
19 + 31454147 = 31454166
43 + 31454123 = 31454166
83 + 31454083 = 31454166
89 + 31454077 = 31454166
113 + 31454053 = 31454166
173 + 31453993 = 31454166

Showing the first eight; more decompositions exist.
