Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704528, here are decompositions:

5 + 8704523 = 8704528
29 + 8704499 = 8704528
47 + 8704481 = 8704528
197 + 8704331 = 8704528
359 + 8704169 = 8704528
461 + 8704067 = 8704528
479 + 8704049 = 8704528
557 + 8703971 = 8704528

Showing the first eight; more decompositions exist.
