Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526948, here are decompositions:

7 + 31526941 = 31526948
67 + 31526881 = 31526948
139 + 31526809 = 31526948
157 + 31526791 = 31526948
199 + 31526749 = 31526948
331 + 31526617 = 31526948
421 + 31526527 = 31526948
577 + 31526371 = 31526948

Showing the first eight; more decompositions exist.
