Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487238, here are decompositions:

19 + 33487219 = 33487238
157 + 33487081 = 33487238
241 + 33486997 = 33487238
397 + 33486841 = 33487238
409 + 33486829 = 33487238
439 + 33486799 = 33487238
487 + 33486751 = 33487238
541 + 33486697 = 33487238

Showing the first eight; more decompositions exist.
