Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724556, here are decompositions:

59 + 8724497 = 8724556
89 + 8724467 = 8724556
179 + 8724377 = 8724556
227 + 8724329 = 8724556
233 + 8724323 = 8724556
263 + 8724293 = 8724556
293 + 8724263 = 8724556
563 + 8723993 = 8724556

Showing the first eight; more decompositions exist.
