Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491838, here are decompositions:

5 + 33491833 = 33491838
7 + 33491831 = 33491838
11 + 33491827 = 33491838
59 + 33491779 = 33491838
71 + 33491767 = 33491838
97 + 33491741 = 33491838
109 + 33491729 = 33491838
157 + 33491681 = 33491838

Showing the first eight; more decompositions exist.
