Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661192, here are decompositions:

11 + 8661181 = 8661192
19 + 8661173 = 8661192
31 + 8661161 = 8661192
73 + 8661119 = 8661192
103 + 8661089 = 8661192
131 + 8661061 = 8661192
149 + 8661043 = 8661192
191 + 8661001 = 8661192

Showing the first eight; more decompositions exist.
