Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621054, here are decompositions:

11 + 31621043 = 31621054
41 + 31621013 = 31621054
53 + 31621001 = 31621054
107 + 31620947 = 31621054
233 + 31620821 = 31621054
317 + 31620737 = 31621054
557 + 31620497 = 31621054
863 + 31620191 = 31621054

Showing the first eight; more decompositions exist.
