Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574898, here are decompositions:

7 + 31574891 = 31574898
11 + 31574887 = 31574898
37 + 31574861 = 31574898
151 + 31574747 = 31574898
197 + 31574701 = 31574898
211 + 31574687 = 31574898
227 + 31574671 = 31574898
241 + 31574657 = 31574898

Showing the first eight; more decompositions exist.
