Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537820, here are decompositions:

11 + 33537809 = 33537820
23 + 33537797 = 33537820
53 + 33537767 = 33537820
131 + 33537689 = 33537820
137 + 33537683 = 33537820
227 + 33537593 = 33537820
263 + 33537557 = 33537820
269 + 33537551 = 33537820

Showing the first eight; more decompositions exist.
