Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65842, here are decompositions:

3 + 65839 = 65842
5 + 65837 = 65842
11 + 65831 = 65842
53 + 65789 = 65842
113 + 65729 = 65842
191 + 65651 = 65842
233 + 65609 = 65842
263 + 65579 = 65842

Showing the first eight; more decompositions exist.
