Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508172, here are decompositions:

13 + 33508159 = 33508172
283 + 33507889 = 33508172
409 + 33507763 = 33508172
421 + 33507751 = 33508172
541 + 33507631 = 33508172
571 + 33507601 = 33508172
631 + 33507541 = 33508172
853 + 33507319 = 33508172

Showing the first eight; more decompositions exist.
