Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639552, here are decompositions:

3 + 8639549 = 8639552
13 + 8639539 = 8639552
109 + 8639443 = 8639552
139 + 8639413 = 8639552
151 + 8639401 = 8639552
409 + 8639143 = 8639552
421 + 8639131 = 8639552
433 + 8639119 = 8639552

Showing the first eight; more decompositions exist.
