Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33475780, here are decompositions:

29 + 33475751 = 33475780
47 + 33475733 = 33475780
71 + 33475709 = 33475780
167 + 33475613 = 33475780
197 + 33475583 = 33475780
227 + 33475553 = 33475780
257 + 33475523 = 33475780
347 + 33475433 = 33475780

Showing the first eight; more decompositions exist.
