Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627198, here are decompositions:

47 + 31627151 = 31627198
107 + 31627091 = 31627198
191 + 31627007 = 31627198
359 + 31626839 = 31627198
401 + 31626797 = 31627198
431 + 31626767 = 31627198
509 + 31626689 = 31627198
641 + 31626557 = 31627198

Showing the first eight; more decompositions exist.
