Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729564, here are decompositions:

7 + 8729557 = 8729564
73 + 8729491 = 8729564
97 + 8729467 = 8729564
163 + 8729401 = 8729564
241 + 8729323 = 8729564
373 + 8729191 = 8729564
433 + 8729131 = 8729564
457 + 8729107 = 8729564

Showing the first eight; more decompositions exist.
