Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477996, here are decompositions:

3 + 31477993 = 31477996
5 + 31477991 = 31477996
29 + 31477967 = 31477996
59 + 31477937 = 31477996
89 + 31477907 = 31477996
113 + 31477883 = 31477996
197 + 31477799 = 31477996
419 + 31477577 = 31477996

Showing the first eight; more decompositions exist.
