Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512978, here are decompositions:

19 + 33512959 = 33512978
97 + 33512881 = 33512978
139 + 33512839 = 33512978
199 + 33512779 = 33512978
307 + 33512671 = 33512978
337 + 33512641 = 33512978
349 + 33512629 = 33512978
409 + 33512569 = 33512978

Showing the first eight; more decompositions exist.
