Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33580880, here are decompositions:

31 + 33580849 = 33580880
61 + 33580819 = 33580880
79 + 33580801 = 33580880
103 + 33580777 = 33580880
139 + 33580741 = 33580880
211 + 33580669 = 33580880
241 + 33580639 = 33580880
283 + 33580597 = 33580880

Showing the first eight; more decompositions exist.
