Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661324, here are decompositions:

13 + 8661311 = 8661324
43 + 8661281 = 8661324
71 + 8661253 = 8661324
73 + 8661251 = 8661324
83 + 8661241 = 8661324
101 + 8661223 = 8661324
107 + 8661217 = 8661324
127 + 8661197 = 8661324

Showing the first eight; more decompositions exist.
