Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649036, here are decompositions:

7 + 8649029 = 8649036
13 + 8649023 = 8649036
83 + 8648953 = 8649036
107 + 8648929 = 8649036
113 + 8648923 = 8649036
157 + 8648879 = 8649036
173 + 8648863 = 8649036
197 + 8648839 = 8649036

Showing the first eight; more decompositions exist.
