Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543890, here are decompositions:

13 + 33543877 = 33543890
181 + 33543709 = 33543890
229 + 33543661 = 33543890
241 + 33543649 = 33543890
307 + 33543583 = 33543890
313 + 33543577 = 33543890
337 + 33543553 = 33543890
379 + 33543511 = 33543890

Showing the first eight; more decompositions exist.
