Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594444, here are decompositions:

23 + 31594421 = 31594444
71 + 31594373 = 31594444
113 + 31594331 = 31594444
173 + 31594271 = 31594444
197 + 31594247 = 31594444
251 + 31594193 = 31594444
281 + 31594163 = 31594444
293 + 31594151 = 31594444

Showing the first eight; more decompositions exist.
