Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581372, here are decompositions:

43 + 33581329 = 33581372
73 + 33581299 = 33581372
109 + 33581263 = 33581372
151 + 33581221 = 33581372
163 + 33581209 = 33581372
241 + 33581131 = 33581372
379 + 33580993 = 33581372
463 + 33580909 = 33581372

Showing the first eight; more decompositions exist.
