Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649032, here are decompositions:

3 + 8649029 = 8649032
31 + 8649001 = 8649032
79 + 8648953 = 8649032
103 + 8648929 = 8649032
109 + 8648923 = 8649032
151 + 8648881 = 8649032
193 + 8648839 = 8649032
199 + 8648833 = 8649032

Showing the first eight; more decompositions exist.
