Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626944, here are decompositions:

61 + 31626883 = 31626944
103 + 31626841 = 31626944
157 + 31626787 = 31626944
277 + 31626667 = 31626944
337 + 31626607 = 31626944
373 + 31626571 = 31626944
397 + 31626547 = 31626944
463 + 31626481 = 31626944

Showing the first eight; more decompositions exist.
