Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717530, here are decompositions:

137 + 8717393 = 8717530
257 + 8717273 = 8717530
317 + 8717213 = 8717530
359 + 8717171 = 8717530
509 + 8717021 = 8717530
587 + 8716943 = 8717530
641 + 8716889 = 8717530
677 + 8716853 = 8717530

Showing the first eight; more decompositions exist.
