Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487788, here are decompositions:

17 + 33487771 = 33487788
29 + 33487759 = 33487788
31 + 33487757 = 33487788
71 + 33487717 = 33487788
107 + 33487681 = 33487788
137 + 33487651 = 33487788
149 + 33487639 = 33487788
157 + 33487631 = 33487788

Showing the first eight; more decompositions exist.
