Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547890, here are decompositions:

17 + 33547873 = 33547890
29 + 33547861 = 33547890
41 + 33547849 = 33547890
43 + 33547847 = 33547890
59 + 33547831 = 33547890
127 + 33547763 = 33547890
151 + 33547739 = 33547890
163 + 33547727 = 33547890

Showing the first eight; more decompositions exist.
