Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491938, here are decompositions:

89 + 33491849 = 33491938
101 + 33491837 = 33491938
107 + 33491831 = 33491938
191 + 33491747 = 33491938
197 + 33491741 = 33491938
257 + 33491681 = 33491938
317 + 33491621 = 33491938
401 + 33491537 = 33491938

Showing the first eight; more decompositions exist.
