Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615018, here are decompositions:

11 + 33615007 = 33615018
67 + 33614951 = 33615018
79 + 33614939 = 33615018
109 + 33614909 = 33615018
131 + 33614887 = 33615018
167 + 33614851 = 33615018
191 + 33614827 = 33615018
211 + 33614807 = 33615018

Showing the first eight; more decompositions exist.
