Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621350, here are decompositions:

11 + 8621339 = 8621350
41 + 8621309 = 8621350
107 + 8621243 = 8621350
113 + 8621237 = 8621350
137 + 8621213 = 8621350
149 + 8621201 = 8621350
167 + 8621183 = 8621350
197 + 8621153 = 8621350

Showing the first eight; more decompositions exist.
