Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581132, here are decompositions:

139 + 33580993 = 33581132
223 + 33580909 = 33581132
229 + 33580903 = 33581132
241 + 33580891 = 33581132
283 + 33580849 = 33581132
313 + 33580819 = 33581132
331 + 33580801 = 33581132
439 + 33580693 = 33581132

Showing the first eight; more decompositions exist.
