Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450998, here are decompositions:

31 + 31450967 = 31450998
37 + 31450961 = 31450998
101 + 31450897 = 31450998
107 + 31450891 = 31450998
151 + 31450847 = 31450998
157 + 31450841 = 31450998
197 + 31450801 = 31450998
211 + 31450787 = 31450998

Showing the first eight; more decompositions exist.
