Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561438, here are decompositions:

59 + 33561379 = 33561438
151 + 33561287 = 33561438
167 + 33561271 = 33561438
241 + 33561197 = 33561438
257 + 33561181 = 33561438
269 + 33561169 = 33561438
277 + 33561161 = 33561438
349 + 33561089 = 33561438

Showing the first eight; more decompositions exist.
