Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761248, here are decompositions:

5 + 8761243 = 8761248
11 + 8761237 = 8761248
71 + 8761177 = 8761248
79 + 8761169 = 8761248
107 + 8761141 = 8761248
109 + 8761139 = 8761248
131 + 8761117 = 8761248
149 + 8761099 = 8761248

Showing the first eight; more decompositions exist.
