Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474806, here are decompositions:

5 + 31474801 = 31474806
23 + 31474783 = 31474806
29 + 31474777 = 31474806
43 + 31474763 = 31474806
59 + 31474747 = 31474806
73 + 31474733 = 31474806
113 + 31474693 = 31474806
137 + 31474669 = 31474806

Showing the first eight; more decompositions exist.
