Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609872, here are decompositions:

23 + 8609849 = 8609872
53 + 8609819 = 8609872
59 + 8609813 = 8609872
233 + 8609639 = 8609872
251 + 8609621 = 8609872
263 + 8609609 = 8609872
281 + 8609591 = 8609872
389 + 8609483 = 8609872

Showing the first eight; more decompositions exist.
