Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477680, here are decompositions:

31 + 33477649 = 33477680
37 + 33477643 = 33477680
127 + 33477553 = 33477680
157 + 33477523 = 33477680
163 + 33477517 = 33477680
199 + 33477481 = 33477680
349 + 33477331 = 33477680
367 + 33477313 = 33477680

Showing the first eight; more decompositions exist.
