Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33559978, here are decompositions:

131 + 33559847 = 33559978
191 + 33559787 = 33559978
197 + 33559781 = 33559978
251 + 33559727 = 33559978
269 + 33559709 = 33559978
311 + 33559667 = 33559978
317 + 33559661 = 33559978
359 + 33559619 = 33559978

Showing the first eight; more decompositions exist.
