Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183942, here are decompositions:

23 + 183919 = 183942
61 + 183881 = 183942
71 + 183871 = 183942
113 + 183829 = 183942
179 + 183763 = 183942
181 + 183761 = 183942
229 + 183713 = 183942
233 + 183709 = 183942

Showing the first eight; more decompositions exist.
