Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525128, here are decompositions:

37 + 33525091 = 33525128
67 + 33525061 = 33525128
79 + 33525049 = 33525128
151 + 33524977 = 33525128
157 + 33524971 = 33525128
409 + 33524719 = 33525128
487 + 33524641 = 33525128
541 + 33524587 = 33525128

Showing the first eight; more decompositions exist.
