Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761340, here are decompositions:

13 + 8761327 = 8761340
37 + 8761303 = 8761340
43 + 8761297 = 8761340
61 + 8761279 = 8761340
97 + 8761243 = 8761340
103 + 8761237 = 8761340
127 + 8761213 = 8761340
163 + 8761177 = 8761340

Showing the first eight; more decompositions exist.
