Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561278, here are decompositions:

7 + 33561271 = 33561278
97 + 33561181 = 33561278
109 + 33561169 = 33561278
139 + 33561139 = 33561278
199 + 33561079 = 33561278
211 + 33561067 = 33561278
271 + 33561007 = 33561278
349 + 33560929 = 33561278

Showing the first eight; more decompositions exist.
