Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693428, here are decompositions:

41 + 8693387 = 8693428
47 + 8693381 = 8693428
59 + 8693369 = 8693428
89 + 8693339 = 8693428
101 + 8693327 = 8693428
197 + 8693231 = 8693428
269 + 8693159 = 8693428
311 + 8693117 = 8693428

Showing the first eight; more decompositions exist.
