Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472128, here are decompositions:

5 + 33472123 = 33472128
17 + 33472111 = 33472128
61 + 33472067 = 33472128
139 + 33471989 = 33472128
149 + 33471979 = 33472128
181 + 33471947 = 33472128
211 + 33471917 = 33472128
229 + 33471899 = 33472128

Showing the first eight; more decompositions exist.
