Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479680, here are decompositions:

11 + 33479669 = 33479680
41 + 33479639 = 33479680
89 + 33479591 = 33479680
107 + 33479573 = 33479680
149 + 33479531 = 33479680
197 + 33479483 = 33479680
233 + 33479447 = 33479680
263 + 33479417 = 33479680

Showing the first eight; more decompositions exist.
