Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479720, here are decompositions:

7 + 33479713 = 33479720
19 + 33479701 = 33479720
103 + 33479617 = 33479720
199 + 33479521 = 33479720
271 + 33479449 = 33479720
349 + 33479371 = 33479720
367 + 33479353 = 33479720
397 + 33479323 = 33479720

Showing the first eight; more decompositions exist.
