Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639406, here are decompositions:

5 + 8639401 = 8639406
43 + 8639363 = 8639406
59 + 8639347 = 8639406
107 + 8639299 = 8639406
157 + 8639249 = 8639406
179 + 8639227 = 8639406
199 + 8639207 = 8639406
229 + 8639177 = 8639406

Showing the first eight; more decompositions exist.
