Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531904, here are decompositions:

17 + 33531887 = 33531904
113 + 33531791 = 33531904
167 + 33531737 = 33531904
233 + 33531671 = 33531904
251 + 33531653 = 33531904
293 + 33531611 = 33531904
317 + 33531587 = 33531904
401 + 33531503 = 33531904

Showing the first eight; more decompositions exist.
