Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521960, here are decompositions:

7 + 33521953 = 33521960
67 + 33521893 = 33521960
97 + 33521863 = 33521960
139 + 33521821 = 33521960
163 + 33521797 = 33521960
229 + 33521731 = 33521960
271 + 33521689 = 33521960
313 + 33521647 = 33521960

Showing the first eight; more decompositions exist.
