Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517728, here are decompositions:

17 + 33517711 = 33517728
31 + 33517697 = 33517728
47 + 33517681 = 33517728
89 + 33517639 = 33517728
109 + 33517619 = 33517728
191 + 33517537 = 33517728
197 + 33517531 = 33517728
229 + 33517499 = 33517728

Showing the first eight; more decompositions exist.
