Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729088, here are decompositions:

7 + 8729081 = 8729088
29 + 8729059 = 8729088
31 + 8729057 = 8729088
37 + 8729051 = 8729088
101 + 8728987 = 8729088
167 + 8728921 = 8729088
191 + 8728897 = 8729088
239 + 8728849 = 8729088

Showing the first eight; more decompositions exist.
