Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594522, here are decompositions:

59 + 31594463 = 31594522
101 + 31594421 = 31594522
149 + 31594373 = 31594522
191 + 31594331 = 31594522
251 + 31594271 = 31594522
359 + 31594163 = 31594522
389 + 31594133 = 31594522
461 + 31594061 = 31594522

Showing the first eight; more decompositions exist.
