Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523290, here are decompositions:

19 + 33523271 = 33523290
29 + 33523261 = 33523290
37 + 33523253 = 33523290
43 + 33523247 = 33523290
61 + 33523229 = 33523290
71 + 33523219 = 33523290
79 + 33523211 = 33523290
109 + 33523181 = 33523290

Showing the first eight; more decompositions exist.
