Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632220, here are decompositions:

97 + 8632123 = 8632220
139 + 8632081 = 8632220
151 + 8632069 = 8632220
193 + 8632027 = 8632220
211 + 8632009 = 8632220
241 + 8631979 = 8632220
277 + 8631943 = 8632220
313 + 8631907 = 8632220

Showing the first eight; more decompositions exist.
