Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520928, here are decompositions:

37 + 33520891 = 33520928
127 + 33520801 = 33520928
151 + 33520777 = 33520928
241 + 33520687 = 33520928
307 + 33520621 = 33520928
367 + 33520561 = 33520928
439 + 33520489 = 33520928
457 + 33520471 = 33520928

Showing the first eight; more decompositions exist.
