Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594788, here are decompositions:

19 + 31594769 = 31594788
31 + 31594757 = 31594788
41 + 31594747 = 31594788
59 + 31594729 = 31594788
61 + 31594727 = 31594788
89 + 31594699 = 31594788
97 + 31594691 = 31594788
107 + 31594681 = 31594788

Showing the first eight; more decompositions exist.
