Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738198, here are decompositions:

37 + 8738161 = 8738198
97 + 8738101 = 8738198
109 + 8738089 = 8738198
127 + 8738071 = 8738198
151 + 8738047 = 8738198
277 + 8737921 = 8738198
331 + 8737867 = 8738198
349 + 8737849 = 8738198

Showing the first eight; more decompositions exist.
