Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33611420, here are decompositions:

13 + 33611407 = 33611420
19 + 33611401 = 33611420
61 + 33611359 = 33611420
67 + 33611353 = 33611420
79 + 33611341 = 33611420
109 + 33611311 = 33611420
127 + 33611293 = 33611420
229 + 33611191 = 33611420

Showing the first eight; more decompositions exist.
