Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672808, here are decompositions:

7 + 8672801 = 8672808
17 + 8672791 = 8672808
19 + 8672789 = 8672808
29 + 8672779 = 8672808
41 + 8672767 = 8672808
101 + 8672707 = 8672808
149 + 8672659 = 8672808
167 + 8672641 = 8672808

Showing the first eight; more decompositions exist.
