Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639376, here are decompositions:

13 + 8639363 = 8639376
29 + 8639347 = 8639376
103 + 8639273 = 8639376
113 + 8639263 = 8639376
127 + 8639249 = 8639376
149 + 8639227 = 8639376
157 + 8639219 = 8639376
199 + 8639177 = 8639376

Showing the first eight; more decompositions exist.
