Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547978, here are decompositions:

5 + 33547973 = 33547978
89 + 33547889 = 33547978
131 + 33547847 = 33547978
239 + 33547739 = 33547978
251 + 33547727 = 33547978
389 + 33547589 = 33547978
449 + 33547529 = 33547978
461 + 33547517 = 33547978

Showing the first eight; more decompositions exist.
