Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503978, here are decompositions:

7 + 33503971 = 33503978
37 + 33503941 = 33503978
97 + 33503881 = 33503978
127 + 33503851 = 33503978
199 + 33503779 = 33503978
229 + 33503749 = 33503978
337 + 33503641 = 33503978
349 + 33503629 = 33503978

Showing the first eight; more decompositions exist.
