Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594384, here are decompositions:

11 + 31594373 = 31594384
53 + 31594331 = 31594384
113 + 31594271 = 31594384
137 + 31594247 = 31594384
191 + 31594193 = 31594384
233 + 31594151 = 31594384
251 + 31594133 = 31594384
401 + 31593983 = 31594384

Showing the first eight; more decompositions exist.
