Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761284, here are decompositions:

5 + 8761279 = 8761284
31 + 8761253 = 8761284
41 + 8761243 = 8761284
47 + 8761237 = 8761284
71 + 8761213 = 8761284
107 + 8761177 = 8761284
127 + 8761157 = 8761284
131 + 8761153 = 8761284

Showing the first eight; more decompositions exist.
