Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491818, here are decompositions:

71 + 33491747 = 33491818
89 + 33491729 = 33491818
137 + 33491681 = 33491818
179 + 33491639 = 33491818
197 + 33491621 = 33491818
251 + 33491567 = 33491818
257 + 33491561 = 33491818
281 + 33491537 = 33491818

Showing the first eight; more decompositions exist.
