Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639530, here are decompositions:

23 + 8639507 = 8639530
71 + 8639459 = 8639530
89 + 8639441 = 8639530
149 + 8639381 = 8639530
167 + 8639363 = 8639530
239 + 8639291 = 8639530
257 + 8639273 = 8639530
269 + 8639261 = 8639530

Showing the first eight; more decompositions exist.
