Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487842, here are decompositions:

23 + 33487819 = 33487842
29 + 33487813 = 33487842
71 + 33487771 = 33487842
83 + 33487759 = 33487842
109 + 33487733 = 33487842
191 + 33487651 = 33487842
211 + 33487631 = 33487842
251 + 33487591 = 33487842

Showing the first eight; more decompositions exist.
