Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636844, here are decompositions:

5 + 8636839 = 8636844
43 + 8636801 = 8636844
53 + 8636791 = 8636844
103 + 8636741 = 8636844
107 + 8636737 = 8636844
131 + 8636713 = 8636844
173 + 8636671 = 8636844
197 + 8636647 = 8636844

Showing the first eight; more decompositions exist.
