Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487428, here are decompositions:

5 + 33487423 = 33487428
11 + 33487417 = 33487428
41 + 33487387 = 33487428
109 + 33487319 = 33487428
127 + 33487301 = 33487428
151 + 33487277 = 33487428
157 + 33487271 = 33487428
167 + 33487261 = 33487428

Showing the first eight; more decompositions exist.
