Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741428, here are decompositions:

107 + 8741321 = 8741428
149 + 8741279 = 8741428
197 + 8741231 = 8741428
281 + 8741147 = 8741428
557 + 8740871 = 8741428
569 + 8740859 = 8741428
587 + 8740841 = 8741428
701 + 8740727 = 8741428

Showing the first eight; more decompositions exist.
