Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526944, here are decompositions:

3 + 31526941 = 31526944
5 + 31526939 = 31526944
17 + 31526927 = 31526944
23 + 31526921 = 31526944
41 + 31526903 = 31526944
167 + 31526777 = 31526944
173 + 31526771 = 31526944
191 + 31526753 = 31526944

Showing the first eight; more decompositions exist.
