Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471890, here are decompositions:

37 + 33471853 = 33471890
79 + 33471811 = 33471890
157 + 33471733 = 33471890
181 + 33471709 = 33471890
223 + 33471667 = 33471890
241 + 33471649 = 33471890
307 + 33471583 = 33471890
313 + 33471577 = 33471890

Showing the first eight; more decompositions exist.
