Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672862, here are decompositions:

31 + 8672831 = 8672862
41 + 8672821 = 8672862
43 + 8672819 = 8672862
61 + 8672801 = 8672862
71 + 8672791 = 8672862
73 + 8672789 = 8672862
83 + 8672779 = 8672862
89 + 8672773 = 8672862

Showing the first eight; more decompositions exist.
