Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454204, here are decompositions:

3 + 31454201 = 31454204
7 + 31454197 = 31454204
13 + 31454191 = 31454204
43 + 31454161 = 31454204
127 + 31454077 = 31454204
151 + 31454053 = 31454204
181 + 31454023 = 31454204
211 + 31453993 = 31454204

Showing the first eight; more decompositions exist.
