Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587490, here are decompositions:

11 + 33587479 = 33587490
19 + 33587471 = 33587490
73 + 33587417 = 33587490
89 + 33587401 = 33587490
127 + 33587363 = 33587490
151 + 33587339 = 33587490
179 + 33587311 = 33587490
227 + 33587263 = 33587490

Showing the first eight; more decompositions exist.
