Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9028, here are decompositions:

17 + 9011 = 9028
29 + 8999 = 9028
59 + 8969 = 9028
167 + 8861 = 9028
179 + 8849 = 9028
191 + 8837 = 9028
197 + 8831 = 9028
281 + 8747 = 9028

Showing the first eight; more decompositions exist.
