Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594752, here are decompositions:

5 + 31594747 = 31594752
23 + 31594729 = 31594752
53 + 31594699 = 31594752
61 + 31594691 = 31594752
71 + 31594681 = 31594752
139 + 31594613 = 31594752
173 + 31594579 = 31594752
179 + 31594573 = 31594752

Showing the first eight; more decompositions exist.
