Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729016, here are decompositions:

29 + 8728987 = 8729016
47 + 8728969 = 8729016
53 + 8728963 = 8729016
73 + 8728943 = 8729016
89 + 8728927 = 8729016
113 + 8728903 = 8729016
167 + 8728849 = 8729016
193 + 8728823 = 8729016

Showing the first eight; more decompositions exist.
