Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581180, here are decompositions:

223 + 33580957 = 33581180
271 + 33580909 = 33581180
277 + 33580903 = 33581180
331 + 33580849 = 33581180
379 + 33580801 = 33581180
439 + 33580741 = 33581180
487 + 33580693 = 33581180
541 + 33580639 = 33581180

Showing the first eight; more decompositions exist.
