Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487944, here are decompositions:

31 + 33487913 = 33487944
37 + 33487907 = 33487944
41 + 33487903 = 33487944
43 + 33487901 = 33487944
67 + 33487877 = 33487944
97 + 33487847 = 33487944
131 + 33487813 = 33487944
173 + 33487771 = 33487944

Showing the first eight; more decompositions exist.
