Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581888, here are decompositions:

19 + 33581869 = 33581888
31 + 33581857 = 33581888
97 + 33581791 = 33581888
127 + 33581761 = 33581888
181 + 33581707 = 33581888
211 + 33581677 = 33581888
271 + 33581617 = 33581888
367 + 33581521 = 33581888

Showing the first eight; more decompositions exist.
