Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639180, here are decompositions:

3 + 8639177 = 8639180
19 + 8639161 = 8639180
31 + 8639149 = 8639180
37 + 8639143 = 8639180
61 + 8639119 = 8639180
73 + 8639107 = 8639180
181 + 8638999 = 8639180
229 + 8638951 = 8639180

Showing the first eight; more decompositions exist.
