Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487164, here are decompositions:

13 + 33487151 = 33487164
17 + 33487147 = 33487164
43 + 33487121 = 33487164
47 + 33487117 = 33487164
83 + 33487081 = 33487164
103 + 33487061 = 33487164
131 + 33487033 = 33487164
167 + 33486997 = 33487164

Showing the first eight; more decompositions exist.
