Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33541720, here are decompositions:

11 + 33541709 = 33541720
53 + 33541667 = 33541720
101 + 33541619 = 33541720
239 + 33541481 = 33541720
257 + 33541463 = 33541720
263 + 33541457 = 33541720
281 + 33541439 = 33541720
293 + 33541427 = 33541720

Showing the first eight; more decompositions exist.
