Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491788, here are decompositions:

41 + 33491747 = 33491788
47 + 33491741 = 33491788
59 + 33491729 = 33491788
107 + 33491681 = 33491788
149 + 33491639 = 33491788
167 + 33491621 = 33491788
227 + 33491561 = 33491788
251 + 33491537 = 33491788

Showing the first eight; more decompositions exist.
