Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639852, here are decompositions:

3 + 8639849 = 8639852
43 + 8639809 = 8639852
73 + 8639779 = 8639852
79 + 8639773 = 8639852
103 + 8639749 = 8639852
139 + 8639713 = 8639852
313 + 8639539 = 8639852
409 + 8639443 = 8639852

Showing the first eight; more decompositions exist.
