Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183940, here are decompositions:

23 + 183917 = 183940
59 + 183881 = 183940
131 + 183809 = 183940
179 + 183761 = 183940
227 + 183713 = 183940
233 + 183707 = 183940
257 + 183683 = 183940
347 + 183593 = 183940

Showing the first eight; more decompositions exist.
