Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729004, here are decompositions:

17 + 8728987 = 8729004
41 + 8728963 = 8729004
61 + 8728943 = 8729004
83 + 8728921 = 8729004
101 + 8728903 = 8729004
103 + 8728901 = 8729004
107 + 8728897 = 8729004
181 + 8728823 = 8729004

Showing the first eight; more decompositions exist.
