Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637238, here are decompositions:

11 + 8637227 = 8637238
59 + 8637179 = 8637238
107 + 8637131 = 8637238
131 + 8637107 = 8637238
179 + 8637059 = 8637238
251 + 8636987 = 8637238
317 + 8636921 = 8637238
419 + 8636819 = 8637238

Showing the first eight; more decompositions exist.
