Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538268, here are decompositions:

37 + 33538231 = 33538268
61 + 33538207 = 33538268
109 + 33538159 = 33538268
139 + 33538129 = 33538268
199 + 33538069 = 33538268
241 + 33538027 = 33538268
307 + 33537961 = 33538268
349 + 33537919 = 33538268

Showing the first eight; more decompositions exist.
