Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507980, here are decompositions:

43 + 33507937 = 33507980
67 + 33507913 = 33507980
73 + 33507907 = 33507980
127 + 33507853 = 33507980
199 + 33507781 = 33507980
229 + 33507751 = 33507980
349 + 33507631 = 33507980
379 + 33507601 = 33507980

Showing the first eight; more decompositions exist.
