Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574256, here are decompositions:

23 + 31574233 = 31574256
53 + 31574203 = 31574256
83 + 31574173 = 31574256
149 + 31574107 = 31574256
157 + 31574099 = 31574256
163 + 31574093 = 31574256
257 + 31573999 = 31574256
397 + 31573859 = 31574256

Showing the first eight; more decompositions exist.
