Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574454, here are decompositions:

5 + 31574449 = 31574454
11 + 31574443 = 31574454
17 + 31574437 = 31574454
127 + 31574327 = 31574454
151 + 31574303 = 31574454
157 + 31574297 = 31574454
193 + 31574261 = 31574454
251 + 31574203 = 31574454

Showing the first eight; more decompositions exist.
