Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531970, here are decompositions:

23 + 33531947 = 33531970
41 + 33531929 = 33531970
47 + 33531923 = 33531970
83 + 33531887 = 33531970
179 + 33531791 = 33531970
233 + 33531737 = 33531970
317 + 33531653 = 33531970
359 + 33531611 = 33531970

Showing the first eight; more decompositions exist.
