Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639288, here are decompositions:

37 + 8639251 = 8639288
61 + 8639227 = 8639288
127 + 8639161 = 8639288
139 + 8639149 = 8639288
157 + 8639131 = 8639288
181 + 8639107 = 8639288
199 + 8639089 = 8639288
277 + 8639011 = 8639288

Showing the first eight; more decompositions exist.
