Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632128, here are decompositions:

5 + 8632123 = 8632128
41 + 8632087 = 8632128
47 + 8632081 = 8632128
59 + 8632069 = 8632128
101 + 8632027 = 8632128
149 + 8631979 = 8632128
151 + 8631977 = 8632128
229 + 8631899 = 8632128

Showing the first eight; more decompositions exist.
