Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561648, here are decompositions:

7 + 33561641 = 33561648
37 + 33561611 = 33561648
41 + 33561607 = 33561648
89 + 33561559 = 33561648
97 + 33561551 = 33561648
179 + 33561469 = 33561648
269 + 33561379 = 33561648
457 + 33561191 = 33561648

Showing the first eight; more decompositions exist.
