Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729898, here are decompositions:

11 + 8729887 = 8729898
17 + 8729881 = 8729898
29 + 8729869 = 8729898
31 + 8729867 = 8729898
59 + 8729839 = 8729898
61 + 8729837 = 8729898
97 + 8729801 = 8729898
131 + 8729767 = 8729898

Showing the first eight; more decompositions exist.
