Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617428, here are decompositions:

11 + 8617417 = 8617428
31 + 8617397 = 8617428
37 + 8617391 = 8617428
47 + 8617381 = 8617428
67 + 8617361 = 8617428
101 + 8617327 = 8617428
109 + 8617319 = 8617428
137 + 8617291 = 8617428

Showing the first eight; more decompositions exist.
