Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33475978, here are decompositions:

47 + 33475931 = 33475978
59 + 33475919 = 33475978
131 + 33475847 = 33475978
227 + 33475751 = 33475978
269 + 33475709 = 33475978
647 + 33475331 = 33475978
677 + 33475301 = 33475978
761 + 33475217 = 33475978

Showing the first eight; more decompositions exist.
