Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639558, here are decompositions:

7 + 8639551 = 8639558
19 + 8639539 = 8639558
97 + 8639461 = 8639558
157 + 8639401 = 8639558
211 + 8639347 = 8639558
307 + 8639251 = 8639558
331 + 8639227 = 8639558
397 + 8639161 = 8639558

Showing the first eight; more decompositions exist.
