Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537390, here are decompositions:

31 + 33537359 = 33537390
97 + 33537293 = 33537390
127 + 33537263 = 33537390
151 + 33537239 = 33537390
157 + 33537233 = 33537390
163 + 33537227 = 33537390
191 + 33537199 = 33537390
199 + 33537191 = 33537390

Showing the first eight; more decompositions exist.
