Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661158, here are decompositions:

97 + 8661061 = 8661158
109 + 8661049 = 8661158
157 + 8661001 = 8661158
211 + 8660947 = 8661158
229 + 8660929 = 8661158
271 + 8660887 = 8661158
487 + 8660671 = 8661158
547 + 8660611 = 8661158

Showing the first eight; more decompositions exist.
