Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729078, here are decompositions:

19 + 8729059 = 8729078
109 + 8728969 = 8729078
151 + 8728927 = 8729078
157 + 8728921 = 8729078
181 + 8728897 = 8729078
229 + 8728849 = 8729078
271 + 8728807 = 8729078
367 + 8728711 = 8729078

Showing the first eight; more decompositions exist.
