Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672838, here are decompositions:

7 + 8672831 = 8672838
17 + 8672821 = 8672838
19 + 8672819 = 8672838
37 + 8672801 = 8672838
47 + 8672791 = 8672838
59 + 8672779 = 8672838
71 + 8672767 = 8672838
107 + 8672731 = 8672838

Showing the first eight; more decompositions exist.
