Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709180, here are decompositions:

31 + 8709149 = 8709180
41 + 8709139 = 8709180
47 + 8709133 = 8709180
59 + 8709121 = 8709180
101 + 8709079 = 8709180
113 + 8709067 = 8709180
173 + 8709007 = 8709180
211 + 8708969 = 8709180

Showing the first eight; more decompositions exist.
