Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724588, here are decompositions:

29 + 8724559 = 8724588
101 + 8724487 = 8724588
109 + 8724479 = 8724588
127 + 8724461 = 8724588
151 + 8724437 = 8724588
167 + 8724421 = 8724588
211 + 8724377 = 8724588
241 + 8724347 = 8724588

Showing the first eight; more decompositions exist.
