Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621344, here are decompositions:

5 + 8621339 = 8621344
101 + 8621243 = 8621344
107 + 8621237 = 8621344
131 + 8621213 = 8621344
191 + 8621153 = 8621344
197 + 8621147 = 8621344
257 + 8621087 = 8621344
293 + 8621051 = 8621344

Showing the first eight; more decompositions exist.
