Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725518, here are decompositions:

7 + 8725511 = 8725518
19 + 8725499 = 8725518
29 + 8725489 = 8725518
37 + 8725481 = 8725518
59 + 8725459 = 8725518
89 + 8725429 = 8725518
97 + 8725421 = 8725518
127 + 8725391 = 8725518

Showing the first eight; more decompositions exist.
