Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672836, here are decompositions:

5 + 8672831 = 8672836
17 + 8672819 = 8672836
47 + 8672789 = 8672836
113 + 8672723 = 8672836
149 + 8672687 = 8672836
197 + 8672639 = 8672836
239 + 8672597 = 8672836
317 + 8672519 = 8672836

Showing the first eight; more decompositions exist.
