Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487230, here are decompositions:

11 + 33487219 = 33487230
37 + 33487193 = 33487230
41 + 33487189 = 33487230
43 + 33487187 = 33487230
67 + 33487163 = 33487230
79 + 33487151 = 33487230
83 + 33487147 = 33487230
109 + 33487121 = 33487230

Showing the first eight; more decompositions exist.
