Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487854, here are decompositions:

7 + 33487847 = 33487854
41 + 33487813 = 33487854
83 + 33487771 = 33487854
97 + 33487757 = 33487854
137 + 33487717 = 33487854
173 + 33487681 = 33487854
223 + 33487631 = 33487854
233 + 33487621 = 33487854

Showing the first eight; more decompositions exist.
