Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621920, here are decompositions:

19 + 33621901 = 33621920
61 + 33621859 = 33621920
97 + 33621823 = 33621920
139 + 33621781 = 33621920
193 + 33621727 = 33621920
229 + 33621691 = 33621920
271 + 33621649 = 33621920
379 + 33621541 = 33621920

Showing the first eight; more decompositions exist.
