Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523218, here are decompositions:

7 + 33523211 = 33523218
37 + 33523181 = 33523218
109 + 33523109 = 33523218
181 + 33523037 = 33523218
191 + 33523027 = 33523218
257 + 33522961 = 33523218
271 + 33522947 = 33523218
317 + 33522901 = 33523218

Showing the first eight; more decompositions exist.
