Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478542, here are decompositions:

11 + 33478531 = 33478542
73 + 33478469 = 33478542
103 + 33478439 = 33478542
109 + 33478433 = 33478542
131 + 33478411 = 33478542
151 + 33478391 = 33478542
211 + 33478331 = 33478542
269 + 33478273 = 33478542

Showing the first eight; more decompositions exist.
