Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471794, here are decompositions:

7 + 31471787 = 31471794
31 + 31471763 = 31471794
83 + 31471711 = 31471794
97 + 31471697 = 31471794
113 + 31471681 = 31471794
127 + 31471667 = 31471794
131 + 31471663 = 31471794
157 + 31471637 = 31471794

Showing the first eight; more decompositions exist.
