Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594896, here are decompositions:

13 + 31594883 = 31594896
19 + 31594877 = 31594896
23 + 31594873 = 31594896
29 + 31594867 = 31594896
83 + 31594813 = 31594896
89 + 31594807 = 31594896
97 + 31594799 = 31594896
127 + 31594769 = 31594896

Showing the first eight; more decompositions exist.
