Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725600, here are decompositions:

29 + 8725571 = 8725600
53 + 8725547 = 8725600
89 + 8725511 = 8725600
101 + 8725499 = 8725600
137 + 8725463 = 8725600
179 + 8725421 = 8725600
239 + 8725361 = 8725600
281 + 8725319 = 8725600

Showing the first eight; more decompositions exist.
