Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972198, here are decompositions:

37 + 972161 = 972198
61 + 972137 = 972198
67 + 972131 = 972198
79 + 972119 = 972198
107 + 972091 = 972198
127 + 972071 = 972198
151 + 972047 = 972198
167 + 972031 = 972198

Showing the first eight; more decompositions exist.
