Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690428, here are decompositions:

17 + 8690411 = 8690428
29 + 8690399 = 8690428
41 + 8690387 = 8690428
137 + 8690291 = 8690428
251 + 8690177 = 8690428
311 + 8690117 = 8690428
359 + 8690069 = 8690428
431 + 8689997 = 8690428

Showing the first eight; more decompositions exist.
