Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66894, here are decompositions:

5 + 66889 = 66894
11 + 66883 = 66894
17 + 66877 = 66894
31 + 66863 = 66894
41 + 66853 = 66894
43 + 66851 = 66894
53 + 66841 = 66894
73 + 66821 = 66894

Showing the first eight; more decompositions exist.
