Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491748, here are decompositions:

7 + 33491741 = 33491748
19 + 33491729 = 33491748
29 + 33491719 = 33491748
67 + 33491681 = 33491748
107 + 33491641 = 33491748
109 + 33491639 = 33491748
127 + 33491621 = 33491748
149 + 33491599 = 33491748

Showing the first eight; more decompositions exist.
