Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594902, here are decompositions:

19 + 31594883 = 31594902
29 + 31594873 = 31594902
41 + 31594861 = 31594902
89 + 31594813 = 31594902
103 + 31594799 = 31594902
173 + 31594729 = 31594902
211 + 31594691 = 31594902
293 + 31594609 = 31594902

Showing the first eight; more decompositions exist.
