Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477938, here are decompositions:

7 + 33477931 = 33477938
379 + 33477559 = 33477938
421 + 33477517 = 33477938
457 + 33477481 = 33477938
547 + 33477391 = 33477938
601 + 33477337 = 33477938
607 + 33477331 = 33477938
631 + 33477307 = 33477938

Showing the first eight; more decompositions exist.
