Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33627278, here are decompositions:

7 + 33627271 = 33627278
79 + 33627199 = 33627278
127 + 33627151 = 33627278
199 + 33627079 = 33627278
229 + 33627049 = 33627278
271 + 33627007 = 33627278
277 + 33627001 = 33627278
379 + 33626899 = 33627278

Showing the first eight; more decompositions exist.
