Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487188, here are decompositions:

37 + 33487151 = 33487188
41 + 33487147 = 33487188
67 + 33487121 = 33487188
71 + 33487117 = 33487188
107 + 33487081 = 33487188
127 + 33487061 = 33487188
139 + 33487049 = 33487188
157 + 33487031 = 33487188

Showing the first eight; more decompositions exist.
