Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33539780, here are decompositions:

31 + 33539749 = 33539780
37 + 33539743 = 33539780
67 + 33539713 = 33539780
73 + 33539707 = 33539780
151 + 33539629 = 33539780
271 + 33539509 = 33539780
349 + 33539431 = 33539780
367 + 33539413 = 33539780

Showing the first eight; more decompositions exist.
