Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645436, here are decompositions:

5 + 8645431 = 8645436
29 + 8645407 = 8645436
83 + 8645353 = 8645436
109 + 8645327 = 8645436
167 + 8645269 = 8645436
179 + 8645257 = 8645436
193 + 8645243 = 8645436
197 + 8645239 = 8645436

Showing the first eight; more decompositions exist.
