Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561430, here are decompositions:

17 + 33561413 = 33561430
41 + 33561389 = 33561430
167 + 33561263 = 33561430
233 + 33561197 = 33561430
239 + 33561191 = 33561430
257 + 33561173 = 33561430
269 + 33561161 = 33561430
431 + 33560999 = 33561430

Showing the first eight; more decompositions exist.
