Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471380, here are decompositions:

37 + 33471343 = 33471380
43 + 33471337 = 33471380
67 + 33471313 = 33471380
109 + 33471271 = 33471380
139 + 33471241 = 33471380
157 + 33471223 = 33471380
211 + 33471169 = 33471380
367 + 33471013 = 33471380

Showing the first eight; more decompositions exist.
