Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549778, here are decompositions:

5 + 33549773 = 33549778
107 + 33549671 = 33549778
179 + 33549599 = 33549778
347 + 33549431 = 33549778
401 + 33549377 = 33549778
419 + 33549359 = 33549778
467 + 33549311 = 33549778
557 + 33549221 = 33549778

Showing the first eight; more decompositions exist.
