Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672100, here are decompositions:

13 + 8672087 = 8672100
37 + 8672063 = 8672100
53 + 8672047 = 8672100
97 + 8672003 = 8672100
109 + 8671991 = 8672100
113 + 8671987 = 8672100
163 + 8671937 = 8672100
181 + 8671919 = 8672100

Showing the first eight; more decompositions exist.
