Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594548, here are decompositions:

47 + 31594501 = 31594548
59 + 31594489 = 31594548
127 + 31594421 = 31594548
149 + 31594399 = 31594548
197 + 31594351 = 31594548
239 + 31594309 = 31594548
277 + 31594271 = 31594548
311 + 31594237 = 31594548

Showing the first eight; more decompositions exist.
