Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479840, here are decompositions:

67 + 33479773 = 33479840
103 + 33479737 = 33479840
127 + 33479713 = 33479840
139 + 33479701 = 33479840
223 + 33479617 = 33479840
307 + 33479533 = 33479840
463 + 33479377 = 33479840
487 + 33479353 = 33479840

Showing the first eight; more decompositions exist.
