Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672860, here are decompositions:

29 + 8672831 = 8672860
41 + 8672819 = 8672860
59 + 8672801 = 8672860
71 + 8672789 = 8672860
137 + 8672723 = 8672860
173 + 8672687 = 8672860
239 + 8672621 = 8672860
263 + 8672597 = 8672860

Showing the first eight; more decompositions exist.
