Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492944, here are decompositions:

11 + 31492933 = 31492944
23 + 31492921 = 31492944
37 + 31492907 = 31492944
97 + 31492847 = 31492944
103 + 31492841 = 31492944
107 + 31492837 = 31492944
163 + 31492781 = 31492944
167 + 31492777 = 31492944

Showing the first eight; more decompositions exist.
