Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485720, here are decompositions:

3 + 33485717 = 33485720
7 + 33485713 = 33485720
19 + 33485701 = 33485720
31 + 33485689 = 33485720
127 + 33485593 = 33485720
193 + 33485527 = 33485720
277 + 33485443 = 33485720
337 + 33485383 = 33485720

Showing the first eight; more decompositions exist.
