Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637244, here are decompositions:

17 + 8637227 = 8637244
41 + 8637203 = 8637244
113 + 8637131 = 8637244
137 + 8637107 = 8637244
191 + 8637053 = 8637244
227 + 8637017 = 8637244
257 + 8636987 = 8637244
443 + 8636801 = 8637244

Showing the first eight; more decompositions exist.
