Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561788, here are decompositions:

19 + 33561769 = 33561788
37 + 33561751 = 33561788
109 + 33561679 = 33561788
181 + 33561607 = 33561788
229 + 33561559 = 33561788
409 + 33561379 = 33561788
607 + 33561181 = 33561788
619 + 33561169 = 33561788

Showing the first eight; more decompositions exist.
