Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672878, here are decompositions:

17 + 8672861 = 8672878
47 + 8672831 = 8672878
59 + 8672819 = 8672878
89 + 8672789 = 8672878
191 + 8672687 = 8672878
239 + 8672639 = 8672878
257 + 8672621 = 8672878
281 + 8672597 = 8672878

Showing the first eight; more decompositions exist.
