Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672880, here are decompositions:

11 + 8672869 = 8672880
19 + 8672861 = 8672880
59 + 8672821 = 8672880
61 + 8672819 = 8672880
79 + 8672801 = 8672880
89 + 8672791 = 8672880
101 + 8672779 = 8672880
107 + 8672773 = 8672880

Showing the first eight; more decompositions exist.
