Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727198, here are decompositions:

19 + 8727179 = 8727198
37 + 8727161 = 8727198
41 + 8727157 = 8727198
79 + 8727119 = 8727198
89 + 8727109 = 8727198
107 + 8727091 = 8727198
131 + 8727067 = 8727198
149 + 8727049 = 8727198

Showing the first eight; more decompositions exist.
