Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33563978, here are decompositions:

67 + 33563911 = 33563978
139 + 33563839 = 33563978
157 + 33563821 = 33563978
229 + 33563749 = 33563978
241 + 33563737 = 33563978
367 + 33563611 = 33563978
397 + 33563581 = 33563978
541 + 33563437 = 33563978

Showing the first eight; more decompositions exist.
