Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727138, here are decompositions:

19 + 8727119 = 8727138
29 + 8727109 = 8727138
47 + 8727091 = 8727138
71 + 8727067 = 8727138
89 + 8727049 = 8727138
107 + 8727031 = 8727138
149 + 8726989 = 8727138
151 + 8726987 = 8727138

Showing the first eight; more decompositions exist.
