Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525990, here are decompositions:

41 + 33525949 = 33525990
59 + 33525931 = 33525990
67 + 33525923 = 33525990
73 + 33525917 = 33525990
89 + 33525901 = 33525990
101 + 33525889 = 33525990
107 + 33525883 = 33525990
131 + 33525859 = 33525990

Showing the first eight; more decompositions exist.
