Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517720, here are decompositions:

23 + 33517697 = 33517720
101 + 33517619 = 33517720
107 + 33517613 = 33517720
239 + 33517481 = 33517720
251 + 33517469 = 33517720
263 + 33517457 = 33517720
347 + 33517373 = 33517720
449 + 33517271 = 33517720

Showing the first eight; more decompositions exist.
