Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479290, here are decompositions:

11 + 33479279 = 33479290
29 + 33479261 = 33479290
59 + 33479231 = 33479290
83 + 33479207 = 33479290
149 + 33479141 = 33479290
227 + 33479063 = 33479290
311 + 33478979 = 33479290
347 + 33478943 = 33479290

Showing the first eight; more decompositions exist.
