Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477920, here are decompositions:

37 + 33477883 = 33477920
103 + 33477817 = 33477920
127 + 33477793 = 33477920
241 + 33477679 = 33477920
271 + 33477649 = 33477920
277 + 33477643 = 33477920
367 + 33477553 = 33477920
397 + 33477523 = 33477920

Showing the first eight; more decompositions exist.
