Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628186, here are decompositions:

5 + 8628181 = 8628186
13 + 8628173 = 8628186
29 + 8628157 = 8628186
37 + 8628149 = 8628186
79 + 8628107 = 8628186
89 + 8628097 = 8628186
109 + 8628077 = 8628186
137 + 8628049 = 8628186

Showing the first eight; more decompositions exist.
