Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639268, here are decompositions:

5 + 8639263 = 8639268
7 + 8639261 = 8639268
17 + 8639251 = 8639268
19 + 8639249 = 8639268
41 + 8639227 = 8639268
61 + 8639207 = 8639268
97 + 8639171 = 8639268
107 + 8639161 = 8639268

Showing the first eight; more decompositions exist.
