Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729580, here are decompositions:

17 + 8729563 = 8729580
23 + 8729557 = 8729580
37 + 8729543 = 8729580
89 + 8729491 = 8729580
113 + 8729467 = 8729580
151 + 8729429 = 8729580
179 + 8729401 = 8729580
191 + 8729389 = 8729580

Showing the first eight; more decompositions exist.
