Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621436, here are decompositions:

7 + 8621429 = 8621436
23 + 8621413 = 8621436
59 + 8621377 = 8621436
97 + 8621339 = 8621436
127 + 8621309 = 8621436
137 + 8621299 = 8621436
193 + 8621243 = 8621436
199 + 8621237 = 8621436

Showing the first eight; more decompositions exist.
