Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594510, here are decompositions:

47 + 31594463 = 31594510
89 + 31594421 = 31594510
137 + 31594373 = 31594510
179 + 31594331 = 31594510
239 + 31594271 = 31594510
263 + 31594247 = 31594510
317 + 31594193 = 31594510
347 + 31594163 = 31594510

Showing the first eight; more decompositions exist.
