Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481520, here are decompositions:

13 + 33481507 = 33481520
97 + 33481423 = 33481520
151 + 33481369 = 33481520
181 + 33481339 = 33481520
199 + 33481321 = 33481520
211 + 33481309 = 33481520
229 + 33481291 = 33481520
421 + 33481099 = 33481520

Showing the first eight; more decompositions exist.
