Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472720, here are decompositions:

23 + 33472697 = 33472720
131 + 33472589 = 33472720
167 + 33472553 = 33472720
227 + 33472493 = 33472720
233 + 33472487 = 33472720
293 + 33472427 = 33472720
389 + 33472331 = 33472720
419 + 33472301 = 33472720

Showing the first eight; more decompositions exist.
