Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525720, here are decompositions:

13 + 33525707 = 33525720
29 + 33525691 = 33525720
73 + 33525647 = 33525720
79 + 33525641 = 33525720
101 + 33525619 = 33525720
113 + 33525607 = 33525720
127 + 33525593 = 33525720
149 + 33525571 = 33525720

Showing the first eight; more decompositions exist.
