Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487194, here are decompositions:

5 + 33487189 = 33487194
7 + 33487187 = 33487194
31 + 33487163 = 33487194
43 + 33487151 = 33487194
47 + 33487147 = 33487194
73 + 33487121 = 33487194
113 + 33487081 = 33487194
163 + 33487031 = 33487194

Showing the first eight; more decompositions exist.
