Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725612, here are decompositions:

3 + 8725609 = 8725612
41 + 8725571 = 8725612
89 + 8725523 = 8725612
101 + 8725511 = 8725612
113 + 8725499 = 8725612
131 + 8725481 = 8725612
149 + 8725463 = 8725612
191 + 8725421 = 8725612

Showing the first eight; more decompositions exist.
