Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626988, here are decompositions:

11 + 31626977 = 31626988
89 + 31626899 = 31626988
131 + 31626857 = 31626988
149 + 31626839 = 31626988
191 + 31626797 = 31626988
431 + 31626557 = 31626988
599 + 31626389 = 31626988
797 + 31626191 = 31626988

Showing the first eight; more decompositions exist.
