Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537438, here are decompositions:

5 + 33537433 = 33537438
19 + 33537419 = 33537438
29 + 33537409 = 33537438
41 + 33537397 = 33537438
79 + 33537359 = 33537438
199 + 33537239 = 33537438
211 + 33537227 = 33537438
239 + 33537199 = 33537438

Showing the first eight; more decompositions exist.
