Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594920, here are decompositions:

13 + 31594907 = 31594920
17 + 31594903 = 31594920
37 + 31594883 = 31594920
43 + 31594877 = 31594920
47 + 31594873 = 31594920
53 + 31594867 = 31594920
59 + 31594861 = 31594920
107 + 31594813 = 31594920

Showing the first eight; more decompositions exist.
