Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594428, here are decompositions:

7 + 31594421 = 31594428
29 + 31594399 = 31594428
97 + 31594331 = 31594428
157 + 31594271 = 31594428
181 + 31594247 = 31594428
191 + 31594237 = 31594428
269 + 31594159 = 31594428
277 + 31594151 = 31594428

Showing the first eight; more decompositions exist.
