Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571880, here are decompositions:

7 + 33571873 = 33571880
31 + 33571849 = 33571880
61 + 33571819 = 33571880
73 + 33571807 = 33571880
79 + 33571801 = 33571880
157 + 33571723 = 33571880
211 + 33571669 = 33571880
241 + 33571639 = 33571880

Showing the first eight; more decompositions exist.
