Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728958, here are decompositions:

31 + 8728927 = 8728958
37 + 8728921 = 8728958
61 + 8728897 = 8728958
109 + 8728849 = 8728958
151 + 8728807 = 8728958
241 + 8728717 = 8728958
331 + 8728627 = 8728958
349 + 8728609 = 8728958

Showing the first eight; more decompositions exist.
