Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538538, here are decompositions:

31 + 33538507 = 33538538
97 + 33538441 = 33538538
151 + 33538387 = 33538538
199 + 33538339 = 33538538
211 + 33538327 = 33538538
307 + 33538231 = 33538538
331 + 33538207 = 33538538
379 + 33538159 = 33538538

Showing the first eight; more decompositions exist.
