Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581330, here are decompositions:

31 + 33581299 = 33581330
43 + 33581287 = 33581330
67 + 33581263 = 33581330
73 + 33581257 = 33581330
109 + 33581221 = 33581330
199 + 33581131 = 33581330
337 + 33580993 = 33581330
373 + 33580957 = 33581330

Showing the first eight; more decompositions exist.
