Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553978, here are decompositions:

11 + 33553967 = 33553978
179 + 33553799 = 33553978
191 + 33553787 = 33553978
239 + 33553739 = 33553978
251 + 33553727 = 33553978
281 + 33553697 = 33553978
317 + 33553661 = 33553978
401 + 33553577 = 33553978

Showing the first eight; more decompositions exist.
