Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520448, here are decompositions:

19 + 33520429 = 33520448
79 + 33520369 = 33520448
127 + 33520321 = 33520448
229 + 33520219 = 33520448
397 + 33520051 = 33520448
499 + 33519949 = 33520448
541 + 33519907 = 33520448
571 + 33519877 = 33520448

Showing the first eight; more decompositions exist.
