Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561836, here are decompositions:

19 + 33561817 = 33561836
37 + 33561799 = 33561836
67 + 33561769 = 33561836
157 + 33561679 = 33561836
163 + 33561673 = 33561836
229 + 33561607 = 33561836
277 + 33561559 = 33561836
367 + 33561469 = 33561836

Showing the first eight; more decompositions exist.
