Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621286, here are decompositions:

5 + 8621281 = 8621286
43 + 8621243 = 8621286
73 + 8621213 = 8621286
97 + 8621189 = 8621286
103 + 8621183 = 8621286
139 + 8621147 = 8621286
197 + 8621089 = 8621286
199 + 8621087 = 8621286

Showing the first eight; more decompositions exist.
