Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531982, here are decompositions:

5 + 33531977 = 33531982
53 + 33531929 = 33531982
59 + 33531923 = 33531982
191 + 33531791 = 33531982
233 + 33531749 = 33531982
311 + 33531671 = 33531982
479 + 33531503 = 33531982
503 + 33531479 = 33531982

Showing the first eight; more decompositions exist.
