Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489890, here are decompositions:

13 + 33489877 = 33489890
19 + 33489871 = 33489890
61 + 33489829 = 33489890
127 + 33489763 = 33489890
151 + 33489739 = 33489890
163 + 33489727 = 33489890
241 + 33489649 = 33489890
271 + 33489619 = 33489890

Showing the first eight; more decompositions exist.
