Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700198, here are decompositions:

5 + 8700193 = 8700198
29 + 8700169 = 8700198
37 + 8700161 = 8700198
127 + 8700071 = 8700198
139 + 8700059 = 8700198
151 + 8700047 = 8700198
167 + 8700031 = 8700198
179 + 8700019 = 8700198

Showing the first eight; more decompositions exist.
