Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725620, here are decompositions:

11 + 8725609 = 8725620
53 + 8725567 = 8725620
73 + 8725547 = 8725620
89 + 8725531 = 8725620
97 + 8725523 = 8725620
109 + 8725511 = 8725620
131 + 8725489 = 8725620
139 + 8725481 = 8725620

Showing the first eight; more decompositions exist.
