Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636862, here are decompositions:

5 + 8636857 = 8636862
23 + 8636839 = 8636862
43 + 8636819 = 8636862
61 + 8636801 = 8636862
71 + 8636791 = 8636862
83 + 8636779 = 8636862
103 + 8636759 = 8636862
149 + 8636713 = 8636862

Showing the first eight; more decompositions exist.
