Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531620, here are decompositions:

7 + 33531613 = 33531620
43 + 33531577 = 33531620
61 + 33531559 = 33531620
79 + 33531541 = 33531620
151 + 33531469 = 33531620
181 + 33531439 = 33531620
193 + 33531427 = 33531620
223 + 33531397 = 33531620

Showing the first eight; more decompositions exist.
