Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454226, here are decompositions:

5 + 31454221 = 31454226
7 + 31454219 = 31454226
29 + 31454197 = 31454226
79 + 31454147 = 31454226
103 + 31454123 = 31454226
109 + 31454117 = 31454226
149 + 31454077 = 31454226
173 + 31454053 = 31454226

Showing the first eight; more decompositions exist.
