Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594740, here are decompositions:

11 + 31594729 = 31594740
13 + 31594727 = 31594740
41 + 31594699 = 31594740
59 + 31594681 = 31594740
113 + 31594627 = 31594740
127 + 31594613 = 31594740
131 + 31594609 = 31594740
157 + 31594583 = 31594740

Showing the first eight; more decompositions exist.
