Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66886, here are decompositions:

3 + 66883 = 66886
23 + 66863 = 66886
89 + 66797 = 66886
137 + 66749 = 66886
173 + 66713 = 66886
233 + 66653 = 66886
257 + 66629 = 66886
269 + 66617 = 66886

Showing the first eight; more decompositions exist.
