Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594248, here are decompositions:

11 + 31594237 = 31594248
89 + 31594159 = 31594248
97 + 31594151 = 31594248
151 + 31594097 = 31594248
167 + 31594081 = 31594248
199 + 31594049 = 31594248
311 + 31593937 = 31594248
317 + 31593931 = 31594248

Showing the first eight; more decompositions exist.
