Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537238, here are decompositions:

5 + 33537233 = 33537238
11 + 33537227 = 33537238
47 + 33537191 = 33537238
71 + 33537167 = 33537238
149 + 33537089 = 33537238
191 + 33537047 = 33537238
239 + 33536999 = 33537238
359 + 33536879 = 33537238

Showing the first eight; more decompositions exist.
