Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66904, here are decompositions:

41 + 66863 = 66904
53 + 66851 = 66904
83 + 66821 = 66904
107 + 66797 = 66904
113 + 66791 = 66904
191 + 66713 = 66904
251 + 66653 = 66904
311 + 66593 = 66904

Showing the first eight; more decompositions exist.
