Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515988, here are decompositions:

17 + 33515971 = 33515988
61 + 33515927 = 33515988
67 + 33515921 = 33515988
71 + 33515917 = 33515988
127 + 33515861 = 33515988
139 + 33515849 = 33515988
151 + 33515837 = 33515988
157 + 33515831 = 33515988

Showing the first eight; more decompositions exist.
