Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639632, here are decompositions:

41 + 8639591 = 8639632
83 + 8639549 = 8639632
101 + 8639531 = 8639632
173 + 8639459 = 8639632
179 + 8639453 = 8639632
191 + 8639441 = 8639632
251 + 8639381 = 8639632
269 + 8639363 = 8639632

Showing the first eight; more decompositions exist.
