Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540794, here are decompositions:

7 + 31540787 = 31540794
11 + 31540783 = 31540794
67 + 31540727 = 31540794
71 + 31540723 = 31540794
101 + 31540693 = 31540794
137 + 31540657 = 31540794
151 + 31540643 = 31540794
157 + 31540637 = 31540794

Showing the first eight; more decompositions exist.
