Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492794, here are decompositions:

13 + 31492781 = 31492794
17 + 31492777 = 31492794
23 + 31492771 = 31492794
37 + 31492757 = 31492794
43 + 31492751 = 31492794
97 + 31492697 = 31492794
103 + 31492691 = 31492794
127 + 31492667 = 31492794

Showing the first eight; more decompositions exist.
