Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33539978, here are decompositions:

7 + 33539971 = 33539978
37 + 33539941 = 33539978
229 + 33539749 = 33539978
271 + 33539707 = 33539978
331 + 33539647 = 33539978
349 + 33539629 = 33539978
487 + 33539491 = 33539978
547 + 33539431 = 33539978

Showing the first eight; more decompositions exist.
