Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471578, here are decompositions:

31 + 33471547 = 33471578
37 + 33471541 = 33471578
67 + 33471511 = 33471578
109 + 33471469 = 33471578
139 + 33471439 = 33471578
181 + 33471397 = 33471578
241 + 33471337 = 33471578
307 + 33471271 = 33471578

Showing the first eight; more decompositions exist.
