Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724564, here are decompositions:

5 + 8724559 = 8724564
53 + 8724511 = 8724564
67 + 8724497 = 8724564
71 + 8724493 = 8724564
97 + 8724467 = 8724564
103 + 8724461 = 8724564
127 + 8724437 = 8724564
193 + 8724371 = 8724564

Showing the first eight; more decompositions exist.
