Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33544872, here are decompositions:

5 + 33544867 = 33544872
29 + 33544843 = 33544872
61 + 33544811 = 33544872
89 + 33544783 = 33544872
139 + 33544733 = 33544872
211 + 33544661 = 33544872
233 + 33544639 = 33544872
241 + 33544631 = 33544872

Showing the first eight; more decompositions exist.
