Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734428, here are decompositions:

7 + 8734421 = 8734428
11 + 8734417 = 8734428
41 + 8734387 = 8734428
61 + 8734367 = 8734428
67 + 8734361 = 8734428
181 + 8734247 = 8734428
191 + 8734237 = 8734428
229 + 8734199 = 8734428

Showing the first eight; more decompositions exist.
