Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672874, here are decompositions:

5 + 8672869 = 8672874
13 + 8672861 = 8672874
43 + 8672831 = 8672874
53 + 8672821 = 8672874
73 + 8672801 = 8672874
83 + 8672791 = 8672874
101 + 8672773 = 8672874
107 + 8672767 = 8672874

Showing the first eight; more decompositions exist.
