Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538890, here are decompositions:

17 + 33538873 = 33538890
23 + 33538867 = 33538890
31 + 33538859 = 33538890
67 + 33538823 = 33538890
89 + 33538801 = 33538890
103 + 33538787 = 33538890
107 + 33538783 = 33538890
127 + 33538763 = 33538890

Showing the first eight; more decompositions exist.
