Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649030, here are decompositions:

7 + 8649023 = 8649030
29 + 8649001 = 8649030
101 + 8648929 = 8649030
107 + 8648923 = 8649030
109 + 8648921 = 8649030
149 + 8648881 = 8649030
151 + 8648879 = 8649030
163 + 8648867 = 8649030

Showing the first eight; more decompositions exist.
