Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523440, here are decompositions:

17 + 33523423 = 33523440
29 + 33523411 = 33523440
31 + 33523409 = 33523440
59 + 33523381 = 33523440
61 + 33523379 = 33523440
113 + 33523327 = 33523440
127 + 33523313 = 33523440
149 + 33523291 = 33523440

Showing the first eight; more decompositions exist.
