Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594976, here are decompositions:

13 + 31594963 = 31594976
73 + 31594903 = 31594976
103 + 31594873 = 31594976
109 + 31594867 = 31594976
163 + 31594813 = 31594976
229 + 31594747 = 31594976
277 + 31594699 = 31594976
349 + 31594627 = 31594976

Showing the first eight; more decompositions exist.
