Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587238, here are decompositions:

5 + 33587233 = 33587238
19 + 33587219 = 33587238
29 + 33587209 = 33587238
127 + 33587111 = 33587238
149 + 33587089 = 33587238
199 + 33587039 = 33587238
227 + 33587011 = 33587238
241 + 33586997 = 33587238

Showing the first eight; more decompositions exist.
