Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538472, here are decompositions:

3 + 33538469 = 33538472
31 + 33538441 = 33538472
151 + 33538321 = 33538472
199 + 33538273 = 33538472
241 + 33538231 = 33538472
313 + 33538159 = 33538472
421 + 33538051 = 33538472
463 + 33538009 = 33538472

Showing the first eight; more decompositions exist.
