Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594910, here are decompositions:

3 + 31594907 = 31594910
7 + 31594903 = 31594910
37 + 31594873 = 31594910
43 + 31594867 = 31594910
97 + 31594813 = 31594910
103 + 31594807 = 31594910
163 + 31594747 = 31594910
181 + 31594729 = 31594910

Showing the first eight; more decompositions exist.
