Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33585720, here are decompositions:

13 + 33585707 = 33585720
17 + 33585703 = 33585720
31 + 33585689 = 33585720
73 + 33585647 = 33585720
79 + 33585641 = 33585720
83 + 33585637 = 33585720
101 + 33585619 = 33585720
107 + 33585613 = 33585720

Showing the first eight; more decompositions exist.
