Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697138, here are decompositions:

5 + 8697133 = 8697138
11 + 8697127 = 8697138
31 + 8697107 = 8697138
41 + 8697097 = 8697138
89 + 8697049 = 8697138
101 + 8697037 = 8697138
139 + 8696999 = 8697138
199 + 8696939 = 8697138

Showing the first eight; more decompositions exist.
