Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487664, here are decompositions:

13 + 33487651 = 33487664
43 + 33487621 = 33487664
73 + 33487591 = 33487664
103 + 33487561 = 33487664
127 + 33487537 = 33487664
151 + 33487513 = 33487664
157 + 33487507 = 33487664
241 + 33487423 = 33487664

Showing the first eight; more decompositions exist.
