Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552944, here are decompositions:

37 + 31552907 = 31552944
53 + 31552891 = 31552944
61 + 31552883 = 31552944
97 + 31552847 = 31552944
113 + 31552831 = 31552944
127 + 31552817 = 31552944
197 + 31552747 = 31552944
211 + 31552733 = 31552944

Showing the first eight; more decompositions exist.
