Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478572, here are decompositions:

11 + 33478561 = 33478572
41 + 33478531 = 33478572
103 + 33478469 = 33478572
139 + 33478433 = 33478572
151 + 33478421 = 33478572
181 + 33478391 = 33478572
241 + 33478331 = 33478572
373 + 33478199 = 33478572

Showing the first eight; more decompositions exist.
