Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487748, here are decompositions:

31 + 33487717 = 33487748
67 + 33487681 = 33487748
97 + 33487651 = 33487748
109 + 33487639 = 33487748
127 + 33487621 = 33487748
157 + 33487591 = 33487748
211 + 33487537 = 33487748
241 + 33487507 = 33487748

Showing the first eight; more decompositions exist.
