Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637344, here are decompositions:

3 + 8637341 = 8637344
7 + 8637337 = 8637344
43 + 8637301 = 8637344
97 + 8637247 = 8637344
181 + 8637163 = 8637344
193 + 8637151 = 8637344
211 + 8637133 = 8637344
241 + 8637103 = 8637344

Showing the first eight; more decompositions exist.
