Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761400, here are decompositions:

61 + 8761339 = 8761400
73 + 8761327 = 8761400
97 + 8761303 = 8761400
103 + 8761297 = 8761400
157 + 8761243 = 8761400
163 + 8761237 = 8761400
223 + 8761177 = 8761400
283 + 8761117 = 8761400

Showing the first eight; more decompositions exist.
