Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594554, here are decompositions:

7 + 31594547 = 31594554
53 + 31594501 = 31594554
181 + 31594373 = 31594554
223 + 31594331 = 31594554
281 + 31594273 = 31594554
283 + 31594271 = 31594554
307 + 31594247 = 31594554
317 + 31594237 = 31594554

Showing the first eight; more decompositions exist.
