Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661252, here are decompositions:

11 + 8661241 = 8661252
13 + 8661239 = 8661252
29 + 8661223 = 8661252
59 + 8661193 = 8661252
71 + 8661181 = 8661252
79 + 8661173 = 8661252
163 + 8661089 = 8661252
191 + 8661061 = 8661252

Showing the first eight; more decompositions exist.
