Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574634, here are decompositions:

71 + 31574563 = 31574634
103 + 31574531 = 31574634
127 + 31574507 = 31574634
137 + 31574497 = 31574634
167 + 31574467 = 31574634
181 + 31574453 = 31574634
191 + 31574443 = 31574634
197 + 31574437 = 31574634

Showing the first eight; more decompositions exist.
