Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537220, here are decompositions:

29 + 33537191 = 33537220
47 + 33537173 = 33537220
53 + 33537167 = 33537220
107 + 33537113 = 33537220
131 + 33537089 = 33537220
173 + 33537047 = 33537220
281 + 33536939 = 33537220
401 + 33536819 = 33537220

Showing the first eight; more decompositions exist.
