Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671180, here are decompositions:

3 + 8671177 = 8671180
29 + 8671151 = 8671180
47 + 8671133 = 8671180
53 + 8671127 = 8671180
83 + 8671097 = 8671180
113 + 8671067 = 8671180
149 + 8671031 = 8671180
173 + 8671007 = 8671180

Showing the first eight; more decompositions exist.
