Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450794, here are decompositions:

5 + 31450789 = 31450794
7 + 31450787 = 31450794
13 + 31450781 = 31450794
31 + 31450763 = 31450794
71 + 31450723 = 31450794
73 + 31450721 = 31450794
127 + 31450667 = 31450794
173 + 31450621 = 31450794

Showing the first eight; more decompositions exist.
