Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538238, here are decompositions:

7 + 33538231 = 33538238
31 + 33538207 = 33538238
79 + 33538159 = 33538238
109 + 33538129 = 33538238
157 + 33538081 = 33538238
211 + 33538027 = 33538238
229 + 33538009 = 33538238
277 + 33537961 = 33538238

Showing the first eight; more decompositions exist.
