Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643048, here are decompositions:

59 + 8642989 = 8643048
97 + 8642951 = 8643048
101 + 8642947 = 8643048
109 + 8642939 = 8643048
137 + 8642911 = 8643048
151 + 8642897 = 8643048
191 + 8642857 = 8643048
199 + 8642849 = 8643048

Showing the first eight; more decompositions exist.
