Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511972, here are decompositions:

5 + 33511967 = 33511972
23 + 33511949 = 33511972
83 + 33511889 = 33511972
293 + 33511679 = 33511972
311 + 33511661 = 33511972
359 + 33511613 = 33511972
401 + 33511571 = 33511972
563 + 33511409 = 33511972

Showing the first eight; more decompositions exist.
