Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561320, here are decompositions:

127 + 33561193 = 33561320
139 + 33561181 = 33561320
151 + 33561169 = 33561320
181 + 33561139 = 33561320
241 + 33561079 = 33561320
307 + 33561013 = 33561320
313 + 33561007 = 33561320
337 + 33560983 = 33561320

Showing the first eight; more decompositions exist.
