Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555278, here are decompositions:

7 + 33555271 = 33555278
19 + 33555259 = 33555278
37 + 33555241 = 33555278
61 + 33555217 = 33555278
79 + 33555199 = 33555278
199 + 33555079 = 33555278
241 + 33555037 = 33555278
307 + 33554971 = 33555278

Showing the first eight; more decompositions exist.
