Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537420, here are decompositions:

11 + 33537409 = 33537420
23 + 33537397 = 33537420
31 + 33537389 = 33537420
61 + 33537359 = 33537420
107 + 33537313 = 33537420
127 + 33537293 = 33537420
157 + 33537263 = 33537420
181 + 33537239 = 33537420

Showing the first eight; more decompositions exist.
