Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627800, here are decompositions:

7 + 31627793 = 31627800
37 + 31627763 = 31627800
47 + 31627753 = 31627800
73 + 31627727 = 31627800
79 + 31627721 = 31627800
151 + 31627649 = 31627800
173 + 31627627 = 31627800
199 + 31627601 = 31627800

Showing the first eight; more decompositions exist.
