Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698138, here are decompositions:

5 + 8698133 = 8698138
17 + 8698121 = 8698138
41 + 8698097 = 8698138
89 + 8698049 = 8698138
101 + 8698037 = 8698138
167 + 8697971 = 8698138
191 + 8697947 = 8698138
269 + 8697869 = 8698138

Showing the first eight; more decompositions exist.
