Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137198, here are decompositions:

7 + 137191 = 137198
67 + 137131 = 137198
79 + 137119 = 137198
109 + 137089 = 137198
199 + 136999 = 137198
211 + 136987 = 137198
337 + 136861 = 137198
349 + 136849 = 137198

Showing the first eight; more decompositions exist.
