Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487918, here are decompositions:

5 + 33487913 = 33487918
11 + 33487907 = 33487918
17 + 33487901 = 33487918
41 + 33487877 = 33487918
59 + 33487859 = 33487918
71 + 33487847 = 33487918
311 + 33487607 = 33487918
467 + 33487451 = 33487918

Showing the first eight; more decompositions exist.
