Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672920, here are decompositions:

23 + 8672897 = 8672920
29 + 8672891 = 8672920
59 + 8672861 = 8672920
89 + 8672831 = 8672920
101 + 8672819 = 8672920
131 + 8672789 = 8672920
197 + 8672723 = 8672920
233 + 8672687 = 8672920

Showing the first eight; more decompositions exist.
