Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594468, here are decompositions:

5 + 31594463 = 31594468
47 + 31594421 = 31594468
137 + 31594331 = 31594468
197 + 31594271 = 31594468
317 + 31594151 = 31594468
419 + 31594049 = 31594468
509 + 31593959 = 31594468
599 + 31593869 = 31594468

Showing the first eight; more decompositions exist.
