Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717538, here are decompositions:

7 + 8717531 = 8717538
17 + 8717521 = 8717538
29 + 8717509 = 8717538
47 + 8717491 = 8717538
149 + 8717389 = 8717538
197 + 8717341 = 8717538
251 + 8717287 = 8717538
337 + 8717201 = 8717538

Showing the first eight; more decompositions exist.
