Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472780, here are decompositions:

83 + 33472697 = 33472780
191 + 33472589 = 33472780
227 + 33472553 = 33472780
281 + 33472499 = 33472780
293 + 33472487 = 33472780
353 + 33472427 = 33472780
449 + 33472331 = 33472780
479 + 33472301 = 33472780

Showing the first eight; more decompositions exist.
