Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561920, here are decompositions:

3 + 33561917 = 33561920
43 + 33561877 = 33561920
103 + 33561817 = 33561920
151 + 33561769 = 33561920
241 + 33561679 = 33561920
313 + 33561607 = 33561920
349 + 33561571 = 33561920
541 + 33561379 = 33561920

Showing the first eight; more decompositions exist.
