Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491790, here are decompositions:

11 + 33491779 = 33491790
23 + 33491767 = 33491790
29 + 33491761 = 33491790
43 + 33491747 = 33491790
61 + 33491729 = 33491790
71 + 33491719 = 33491790
97 + 33491693 = 33491790
109 + 33491681 = 33491790

Showing the first eight; more decompositions exist.
