Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487980, here are decompositions:

7 + 33487973 = 33487980
11 + 33487969 = 33487980
67 + 33487913 = 33487980
73 + 33487907 = 33487980
79 + 33487901 = 33487980
103 + 33487877 = 33487980
167 + 33487813 = 33487980
223 + 33487757 = 33487980

Showing the first eight; more decompositions exist.
