Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662180, here are decompositions:

3 + 8662177 = 8662180
11 + 8662169 = 8662180
29 + 8662151 = 8662180
47 + 8662133 = 8662180
53 + 8662127 = 8662180
71 + 8662109 = 8662180
89 + 8662091 = 8662180
101 + 8662079 = 8662180

Showing the first eight; more decompositions exist.
