Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700186, here are decompositions:

17 + 8700169 = 8700186
73 + 8700113 = 8700186
107 + 8700079 = 8700186
127 + 8700059 = 8700186
139 + 8700047 = 8700186
149 + 8700037 = 8700186
167 + 8700019 = 8700186
179 + 8700007 = 8700186

Showing the first eight; more decompositions exist.
