Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487888, here are decompositions:

11 + 33487877 = 33487888
29 + 33487859 = 33487888
41 + 33487847 = 33487888
131 + 33487757 = 33487888
257 + 33487631 = 33487888
281 + 33487607 = 33487888
569 + 33487319 = 33487888
587 + 33487301 = 33487888

Showing the first eight; more decompositions exist.
