Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538172, here are decompositions:

13 + 33538159 = 33538172
43 + 33538129 = 33538172
103 + 33538069 = 33538172
163 + 33538009 = 33538172
211 + 33537961 = 33538172
463 + 33537709 = 33538172
601 + 33537571 = 33538172
631 + 33537541 = 33538172

Showing the first eight; more decompositions exist.
