Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670528, here are decompositions:

5 + 8670523 = 8670528
19 + 8670509 = 8670528
29 + 8670499 = 8670528
37 + 8670491 = 8670528
47 + 8670481 = 8670528
131 + 8670397 = 8670528
157 + 8670371 = 8670528
197 + 8670331 = 8670528

Showing the first eight; more decompositions exist.
