Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706180, here are decompositions:

11 + 8706169 = 8706180
17 + 8706163 = 8706180
31 + 8706149 = 8706180
73 + 8706107 = 8706180
79 + 8706101 = 8706180
101 + 8706079 = 8706180
107 + 8706073 = 8706180
167 + 8706013 = 8706180

Showing the first eight; more decompositions exist.
