Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661330, here are decompositions:

19 + 8661311 = 8661330
79 + 8661251 = 8661330
89 + 8661241 = 8661330
107 + 8661223 = 8661330
113 + 8661217 = 8661330
127 + 8661203 = 8661330
137 + 8661193 = 8661330
149 + 8661181 = 8661330

Showing the first eight; more decompositions exist.
