Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485640, here are decompositions:

47 + 33485593 = 33485640
73 + 33485567 = 33485640
103 + 33485537 = 33485640
113 + 33485527 = 33485640
127 + 33485513 = 33485640
157 + 33485483 = 33485640
163 + 33485477 = 33485640
197 + 33485443 = 33485640

Showing the first eight; more decompositions exist.
