Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587390, here are decompositions:

19 + 33587371 = 33587390
43 + 33587347 = 33587390
79 + 33587311 = 33587390
103 + 33587287 = 33587390
127 + 33587263 = 33587390
139 + 33587251 = 33587390
157 + 33587233 = 33587390
181 + 33587209 = 33587390

Showing the first eight; more decompositions exist.
