Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478160, here are decompositions:

7 + 33478153 = 33478160
97 + 33478063 = 33478160
151 + 33478009 = 33478160
229 + 33477931 = 33478160
277 + 33477883 = 33478160
367 + 33477793 = 33478160
601 + 33477559 = 33478160
607 + 33477553 = 33478160

Showing the first eight; more decompositions exist.
