Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639550, here are decompositions:

11 + 8639539 = 8639550
19 + 8639531 = 8639550
43 + 8639507 = 8639550
89 + 8639461 = 8639550
97 + 8639453 = 8639550
107 + 8639443 = 8639550
109 + 8639441 = 8639550
137 + 8639413 = 8639550

Showing the first eight; more decompositions exist.
