Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594550, here are decompositions:

3 + 31594547 = 31594550
61 + 31594489 = 31594550
151 + 31594399 = 31594550
157 + 31594393 = 31594550
199 + 31594351 = 31594550
241 + 31594309 = 31594550
277 + 31594273 = 31594550
313 + 31594237 = 31594550

Showing the first eight; more decompositions exist.
