Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561986, here are decompositions:

37 + 33561949 = 33561986
43 + 33561943 = 33561986
67 + 33561919 = 33561986
109 + 33561877 = 33561986
307 + 33561679 = 33561986
313 + 33561673 = 33561986
379 + 33561607 = 33561986
607 + 33561379 = 33561986

Showing the first eight; more decompositions exist.
