Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717520, here are decompositions:

11 + 8717509 = 8717520
29 + 8717491 = 8717520
127 + 8717393 = 8717520
131 + 8717389 = 8717520
167 + 8717353 = 8717520
179 + 8717341 = 8717520
191 + 8717329 = 8717520
197 + 8717323 = 8717520

Showing the first eight; more decompositions exist.
