Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485772, here are decompositions:

31 + 33485741 = 33485772
41 + 33485731 = 33485772
59 + 33485713 = 33485772
71 + 33485701 = 33485772
83 + 33485689 = 33485772
109 + 33485663 = 33485772
179 + 33485593 = 33485772
373 + 33485399 = 33485772

Showing the first eight; more decompositions exist.
