Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594866, here are decompositions:

5 + 31594861 = 31594866
53 + 31594813 = 31594866
59 + 31594807 = 31594866
67 + 31594799 = 31594866
97 + 31594769 = 31594866
109 + 31594757 = 31594866
137 + 31594729 = 31594866
139 + 31594727 = 31594866

Showing the first eight; more decompositions exist.
