Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632278, here are decompositions:

41 + 8632237 = 8632278
59 + 8632219 = 8632278
139 + 8632139 = 8632278
191 + 8632087 = 8632278
197 + 8632081 = 8632278
251 + 8632027 = 8632278
269 + 8632009 = 8632278
367 + 8631911 = 8632278

Showing the first eight; more decompositions exist.
