Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561520, here are decompositions:

17 + 33561503 = 33561520
107 + 33561413 = 33561520
131 + 33561389 = 33561520
233 + 33561287 = 33561520
257 + 33561263 = 33561520
347 + 33561173 = 33561520
359 + 33561161 = 33561520
431 + 33561089 = 33561520

Showing the first eight; more decompositions exist.
