Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8692428, here are decompositions:

7 + 8692421 = 8692428
11 + 8692417 = 8692428
89 + 8692339 = 8692428
97 + 8692331 = 8692428
109 + 8692319 = 8692428
131 + 8692297 = 8692428
139 + 8692289 = 8692428
149 + 8692279 = 8692428

Showing the first eight; more decompositions exist.
