Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531858, here are decompositions:

5 + 33531853 = 33531858
11 + 33531847 = 33531858
67 + 33531791 = 33531858
109 + 33531749 = 33531858
179 + 33531679 = 33531858
197 + 33531661 = 33531858
271 + 33531587 = 33531858
281 + 33531577 = 33531858

Showing the first eight; more decompositions exist.
