Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471280, here are decompositions:

107 + 33471173 = 33471280
113 + 33471167 = 33471280
149 + 33471131 = 33471280
191 + 33471089 = 33471280
281 + 33470999 = 33471280
347 + 33470933 = 33471280
383 + 33470897 = 33471280
431 + 33470849 = 33471280

Showing the first eight; more decompositions exist.
