Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531666, here are decompositions:

5 + 33531661 = 33531666
13 + 33531653 = 33531666
53 + 33531613 = 33531666
79 + 33531587 = 33531666
89 + 33531577 = 33531666
107 + 33531559 = 33531666
139 + 33531527 = 33531666
163 + 33531503 = 33531666

Showing the first eight; more decompositions exist.
