Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587420, here are decompositions:

3 + 33587417 = 33587420
19 + 33587401 = 33587420
73 + 33587347 = 33587420
109 + 33587311 = 33587420
157 + 33587263 = 33587420
211 + 33587209 = 33587420
277 + 33587143 = 33587420
331 + 33587089 = 33587420

Showing the first eight; more decompositions exist.
