Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487790, here are decompositions:

19 + 33487771 = 33487790
31 + 33487759 = 33487790
73 + 33487717 = 33487790
109 + 33487681 = 33487790
139 + 33487651 = 33487790
151 + 33487639 = 33487790
199 + 33487591 = 33487790
211 + 33487579 = 33487790

Showing the first eight; more decompositions exist.
