Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671600, here are decompositions:

11 + 8671589 = 8671600
17 + 8671583 = 8671600
83 + 8671517 = 8671600
89 + 8671511 = 8671600
101 + 8671499 = 8671600
131 + 8671469 = 8671600
137 + 8671463 = 8671600
173 + 8671427 = 8671600

Showing the first eight; more decompositions exist.
