Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487678, here are decompositions:

47 + 33487631 = 33487678
71 + 33487607 = 33487678
167 + 33487511 = 33487678
227 + 33487451 = 33487678
359 + 33487319 = 33487678
401 + 33487277 = 33487678
431 + 33487247 = 33487678
491 + 33487187 = 33487678

Showing the first eight; more decompositions exist.
