Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661294, here are decompositions:

13 + 8661281 = 8661294
41 + 8661253 = 8661294
43 + 8661251 = 8661294
53 + 8661241 = 8661294
71 + 8661223 = 8661294
97 + 8661197 = 8661294
101 + 8661193 = 8661294
113 + 8661181 = 8661294

Showing the first eight; more decompositions exist.
