Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644152, here are decompositions:

5 + 8644147 = 8644152
29 + 8644123 = 8644152
61 + 8644091 = 8644152
71 + 8644081 = 8644152
103 + 8644049 = 8644152
193 + 8643959 = 8644152
199 + 8643953 = 8644152
211 + 8643941 = 8644152

Showing the first eight; more decompositions exist.
