Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639498, here are decompositions:

37 + 8639461 = 8639498
97 + 8639401 = 8639498
151 + 8639347 = 8639498
199 + 8639299 = 8639498
271 + 8639227 = 8639498
337 + 8639161 = 8639498
349 + 8639149 = 8639498
367 + 8639131 = 8639498

Showing the first eight; more decompositions exist.
