Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581136, here are decompositions:

5 + 33581131 = 33581136
13 + 33581123 = 33581136
19 + 33581117 = 33581136
37 + 33581099 = 33581136
109 + 33581027 = 33581136
179 + 33580957 = 33581136
227 + 33580909 = 33581136
229 + 33580907 = 33581136

Showing the first eight; more decompositions exist.
