Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558380, here are decompositions:

7 + 33558373 = 33558380
109 + 33558271 = 33558380
127 + 33558253 = 33558380
313 + 33558067 = 33558380
337 + 33558043 = 33558380
439 + 33557941 = 33558380
463 + 33557917 = 33558380
487 + 33557893 = 33558380

Showing the first eight; more decompositions exist.
