Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508890, here are decompositions:

31 + 33508859 = 33508890
43 + 33508847 = 33508890
59 + 33508831 = 33508890
61 + 33508829 = 33508890
73 + 33508817 = 33508890
83 + 33508807 = 33508890
89 + 33508801 = 33508890
109 + 33508781 = 33508890

Showing the first eight; more decompositions exist.
