Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725584, here are decompositions:

13 + 8725571 = 8725584
17 + 8725567 = 8725584
37 + 8725547 = 8725584
53 + 8725531 = 8725584
61 + 8725523 = 8725584
73 + 8725511 = 8725584
103 + 8725481 = 8725584
163 + 8725421 = 8725584

Showing the first eight; more decompositions exist.
