Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742556, here are decompositions:

5 + 8742551 = 8742556
59 + 8742497 = 8742556
107 + 8742449 = 8742556
197 + 8742359 = 8742556
239 + 8742317 = 8742556
293 + 8742263 = 8742556
359 + 8742197 = 8742556
479 + 8742077 = 8742556

Showing the first eight; more decompositions exist.
