Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728974, here are decompositions:

5 + 8728969 = 8728974
11 + 8728963 = 8728974
31 + 8728943 = 8728974
47 + 8728927 = 8728974
53 + 8728921 = 8728974
71 + 8728903 = 8728974
73 + 8728901 = 8728974
151 + 8728823 = 8728974

Showing the first eight; more decompositions exist.
