Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537442, here are decompositions:

5 + 33537437 = 33537442
23 + 33537419 = 33537442
53 + 33537389 = 33537442
83 + 33537359 = 33537442
149 + 33537293 = 33537442
179 + 33537263 = 33537442
251 + 33537191 = 33537442
269 + 33537173 = 33537442

Showing the first eight; more decompositions exist.
