Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755428, here are decompositions:

29 + 8755399 = 8755428
47 + 8755381 = 8755428
79 + 8755349 = 8755428
89 + 8755339 = 8755428
107 + 8755321 = 8755428
109 + 8755319 = 8755428
131 + 8755297 = 8755428
137 + 8755291 = 8755428

Showing the first eight; more decompositions exist.
