Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525140, here are decompositions:

3 + 33525137 = 33525140
79 + 33525061 = 33525140
127 + 33525013 = 33525140
163 + 33524977 = 33525140
331 + 33524809 = 33525140
367 + 33524773 = 33525140
421 + 33524719 = 33525140
487 + 33524653 = 33525140

Showing the first eight; more decompositions exist.
