Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724828, here are decompositions:

29 + 8724799 = 8724828
41 + 8724787 = 8724828
89 + 8724739 = 8724828
107 + 8724721 = 8724828
109 + 8724719 = 8724828
131 + 8724697 = 8724828
179 + 8724649 = 8724828
197 + 8724631 = 8724828

Showing the first eight; more decompositions exist.
