Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487936, here are decompositions:

23 + 33487913 = 33487936
29 + 33487907 = 33487936
59 + 33487877 = 33487936
89 + 33487847 = 33487936
179 + 33487757 = 33487936
593 + 33487343 = 33487936
617 + 33487319 = 33487936
659 + 33487277 = 33487936

Showing the first eight; more decompositions exist.
