Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532198, here are decompositions:

31 + 31532167 = 31532198
109 + 31532089 = 31532198
127 + 31532071 = 31532198
277 + 31531921 = 31532198
571 + 31531627 = 31532198
619 + 31531579 = 31532198
727 + 31531471 = 31532198
829 + 31531369 = 31532198

Showing the first eight; more decompositions exist.
