Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487974, here are decompositions:

5 + 33487969 = 33487974
61 + 33487913 = 33487974
67 + 33487907 = 33487974
71 + 33487903 = 33487974
73 + 33487901 = 33487974
97 + 33487877 = 33487974
127 + 33487847 = 33487974
241 + 33487733 = 33487974

Showing the first eight; more decompositions exist.
