Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487990, here are decompositions:

17 + 33487973 = 33487990
83 + 33487907 = 33487990
89 + 33487901 = 33487990
113 + 33487877 = 33487990
131 + 33487859 = 33487990
233 + 33487757 = 33487990
257 + 33487733 = 33487990
359 + 33487631 = 33487990

Showing the first eight; more decompositions exist.
