Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623992, here are decompositions:

3 + 31623989 = 31623992
13 + 31623979 = 31623992
61 + 31623931 = 31623992
271 + 31623721 = 31623992
571 + 31623421 = 31623992
619 + 31623373 = 31623992
769 + 31623223 = 31623992
811 + 31623181 = 31623992

Showing the first eight; more decompositions exist.
