Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637444, here are decompositions:

17 + 8637427 = 8637444
71 + 8637373 = 8637444
103 + 8637341 = 8637444
107 + 8637337 = 8637444
181 + 8637263 = 8637444
191 + 8637253 = 8637444
197 + 8637247 = 8637444
241 + 8637203 = 8637444

Showing the first eight; more decompositions exist.
