Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574196, here are decompositions:

23 + 31574173 = 31574196
89 + 31574107 = 31574196
97 + 31574099 = 31574196
103 + 31574093 = 31574196
149 + 31574047 = 31574196
197 + 31573999 = 31574196
229 + 31573967 = 31574196
239 + 31573957 = 31574196

Showing the first eight; more decompositions exist.
