Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708180, here are decompositions:

7 + 8708173 = 8708180
37 + 8708143 = 8708180
79 + 8708101 = 8708180
109 + 8708071 = 8708180
163 + 8708017 = 8708180
181 + 8707999 = 8708180
211 + 8707969 = 8708180
241 + 8707939 = 8708180

Showing the first eight; more decompositions exist.
