Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672872, here are decompositions:

3 + 8672869 = 8672872
11 + 8672861 = 8672872
41 + 8672831 = 8672872
53 + 8672819 = 8672872
71 + 8672801 = 8672872
83 + 8672789 = 8672872
149 + 8672723 = 8672872
233 + 8672639 = 8672872

Showing the first eight; more decompositions exist.
