Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525618, here are decompositions:

11 + 33525607 = 33525618
47 + 33525571 = 33525618
67 + 33525551 = 33525618
89 + 33525529 = 33525618
101 + 33525517 = 33525618
127 + 33525491 = 33525618
131 + 33525487 = 33525618
179 + 33525439 = 33525618

Showing the first eight; more decompositions exist.
