Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561428, here are decompositions:

67 + 33561361 = 33561428
157 + 33561271 = 33561428
349 + 33561079 = 33561428
409 + 33561019 = 33561428
421 + 33561007 = 33561428
499 + 33560929 = 33561428
547 + 33560881 = 33561428
577 + 33560851 = 33561428

Showing the first eight; more decompositions exist.
