Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477520, here are decompositions:

3 + 33477517 = 33477520
29 + 33477491 = 33477520
47 + 33477473 = 33477520
53 + 33477467 = 33477520
107 + 33477413 = 33477520
173 + 33477347 = 33477520
269 + 33477251 = 33477520
281 + 33477239 = 33477520

Showing the first eight; more decompositions exist.
