Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724798, here are decompositions:

11 + 8724787 = 8724798
59 + 8724739 = 8724798
79 + 8724719 = 8724798
101 + 8724697 = 8724798
149 + 8724649 = 8724798
157 + 8724641 = 8724798
167 + 8724631 = 8724798
179 + 8724619 = 8724798

Showing the first eight; more decompositions exist.
