Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520640, here are decompositions:

19 + 33520621 = 33520640
37 + 33520603 = 33520640
79 + 33520561 = 33520640
151 + 33520489 = 33520640
163 + 33520477 = 33520640
211 + 33520429 = 33520640
271 + 33520369 = 33520640
277 + 33520363 = 33520640

Showing the first eight; more decompositions exist.
