Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521972, here are decompositions:

13 + 33521959 = 33521972
19 + 33521953 = 33521972
79 + 33521893 = 33521972
109 + 33521863 = 33521972
151 + 33521821 = 33521972
241 + 33521731 = 33521972
271 + 33521701 = 33521972
283 + 33521689 = 33521972

Showing the first eight; more decompositions exist.
