Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632280, here are decompositions:

43 + 8632237 = 8632280
61 + 8632219 = 8632280
157 + 8632123 = 8632280
193 + 8632087 = 8632280
199 + 8632081 = 8632280
211 + 8632069 = 8632280
271 + 8632009 = 8632280
277 + 8632003 = 8632280

Showing the first eight; more decompositions exist.
