Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538520, here are decompositions:

3 + 33538517 = 33538520
13 + 33538507 = 33538520
73 + 33538447 = 33538520
79 + 33538441 = 33538520
181 + 33538339 = 33538520
193 + 33538327 = 33538520
199 + 33538321 = 33538520
313 + 33538207 = 33538520

Showing the first eight; more decompositions exist.
