Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9072, here are decompositions:

5 + 9067 = 9072
13 + 9059 = 9072
23 + 9049 = 9072
29 + 9043 = 9072
31 + 9041 = 9072
43 + 9029 = 9072
59 + 9013 = 9072
61 + 9011 = 9072

Showing the first eight; more decompositions exist.
