Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761290, here are decompositions:

11 + 8761279 = 8761290
37 + 8761253 = 8761290
47 + 8761243 = 8761290
53 + 8761237 = 8761290
113 + 8761177 = 8761290
137 + 8761153 = 8761290
149 + 8761141 = 8761290
151 + 8761139 = 8761290

Showing the first eight; more decompositions exist.
