Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637180, here are decompositions:

17 + 8637163 = 8637180
29 + 8637151 = 8637180
47 + 8637133 = 8637180
61 + 8637119 = 8637180
73 + 8637107 = 8637180
89 + 8637091 = 8637180
113 + 8637067 = 8637180
127 + 8637053 = 8637180

Showing the first eight; more decompositions exist.
