Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487132, here are decompositions:

11 + 33487121 = 33487132
71 + 33487061 = 33487132
83 + 33487049 = 33487132
101 + 33487031 = 33487132
179 + 33486953 = 33487132
191 + 33486941 = 33487132
269 + 33486863 = 33487132
383 + 33486749 = 33487132

Showing the first eight; more decompositions exist.
