Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561144, here are decompositions:

5 + 33561139 = 33561144
41 + 33561103 = 33561144
131 + 33561013 = 33561144
137 + 33561007 = 33561144
193 + 33560951 = 33561144
263 + 33560881 = 33561144
293 + 33560851 = 33561144
311 + 33560833 = 33561144

Showing the first eight; more decompositions exist.
