Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717242, here are decompositions:

3 + 8717239 = 8717242
29 + 8717213 = 8717242
41 + 8717201 = 8717242
71 + 8717171 = 8717242
353 + 8716889 = 8717242
389 + 8716853 = 8717242
563 + 8716679 = 8717242
659 + 8716583 = 8717242

Showing the first eight; more decompositions exist.
