Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66844, here are decompositions:

3 + 66841 = 66844
23 + 66821 = 66844
47 + 66797 = 66844
53 + 66791 = 66844
131 + 66713 = 66844
191 + 66653 = 66844
227 + 66617 = 66844
251 + 66593 = 66844

Showing the first eight; more decompositions exist.
