Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636872, here are decompositions:

3 + 8636869 = 8636872
53 + 8636819 = 8636872
71 + 8636801 = 8636872
113 + 8636759 = 8636872
131 + 8636741 = 8636872
239 + 8636633 = 8636872
269 + 8636603 = 8636872
281 + 8636591 = 8636872

Showing the first eight; more decompositions exist.
