Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520778, here are decompositions:

19 + 33520759 = 33520778
97 + 33520681 = 33520778
157 + 33520621 = 33520778
307 + 33520471 = 33520778
349 + 33520429 = 33520778
409 + 33520369 = 33520778
457 + 33520321 = 33520778
547 + 33520231 = 33520778

Showing the first eight; more decompositions exist.
