Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712180, here are decompositions:

7 + 8712173 = 8712180
11 + 8712169 = 8712180
13 + 8712167 = 8712180
17 + 8712163 = 8712180
23 + 8712157 = 8712180
31 + 8712149 = 8712180
47 + 8712133 = 8712180
67 + 8712113 = 8712180

Showing the first eight; more decompositions exist.
