Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993942, here are decompositions:

23 + 993919 = 993942
29 + 993913 = 993942
73 + 993869 = 993942
101 + 993841 = 993942
149 + 993793 = 993942
163 + 993779 = 993942
179 + 993763 = 993942
239 + 993703 = 993942

Showing the first eight; more decompositions exist.
