Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525780, here are decompositions:

7 + 33525773 = 33525780
23 + 33525757 = 33525780
53 + 33525727 = 33525780
73 + 33525707 = 33525780
89 + 33525691 = 33525780
137 + 33525643 = 33525780
139 + 33525641 = 33525780
173 + 33525607 = 33525780

Showing the first eight; more decompositions exist.
