Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471490, here are decompositions:

11 + 33471479 = 33471490
53 + 33471437 = 33471490
131 + 33471359 = 33471490
137 + 33471353 = 33471490
167 + 33471323 = 33471490
317 + 33471173 = 33471490
359 + 33471131 = 33471490
401 + 33471089 = 33471490

Showing the first eight; more decompositions exist.
