Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33627290, here are decompositions:

13 + 33627277 = 33627290
19 + 33627271 = 33627290
127 + 33627163 = 33627290
139 + 33627151 = 33627290
211 + 33627079 = 33627290
241 + 33627049 = 33627290
283 + 33627007 = 33627290
313 + 33626977 = 33627290

Showing the first eight; more decompositions exist.
