Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706186, here are decompositions:

17 + 8706169 = 8706186
23 + 8706163 = 8706186
37 + 8706149 = 8706186
79 + 8706107 = 8706186
107 + 8706079 = 8706186
113 + 8706073 = 8706186
127 + 8706059 = 8706186
173 + 8706013 = 8706186

Showing the first eight; more decompositions exist.
