Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729998, here are decompositions:

59 + 8729939 = 8729998
131 + 8729867 = 8729998
149 + 8729849 = 8729998
197 + 8729801 = 8729998
269 + 8729729 = 8729998
281 + 8729717 = 8729998
317 + 8729681 = 8729998
569 + 8729429 = 8729998

Showing the first eight; more decompositions exist.
