Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594836, here are decompositions:

23 + 31594813 = 31594836
29 + 31594807 = 31594836
37 + 31594799 = 31594836
67 + 31594769 = 31594836
79 + 31594757 = 31594836
89 + 31594747 = 31594836
107 + 31594729 = 31594836
109 + 31594727 = 31594836

Showing the first eight; more decompositions exist.
