Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587172, here are decompositions:

11 + 33587161 = 33587172
29 + 33587143 = 33587172
61 + 33587111 = 33587172
83 + 33587089 = 33587172
181 + 33586991 = 33587172
233 + 33586939 = 33587172
251 + 33586921 = 33587172
293 + 33586879 = 33587172

Showing the first eight; more decompositions exist.
