Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594916, here are decompositions:

13 + 31594903 = 31594916
43 + 31594873 = 31594916
103 + 31594813 = 31594916
109 + 31594807 = 31594916
307 + 31594609 = 31594916
337 + 31594579 = 31594916
487 + 31594429 = 31594916
523 + 31594393 = 31594916

Showing the first eight; more decompositions exist.
