Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82742, here are decompositions:

13 + 82729 = 82742
19 + 82723 = 82742
43 + 82699 = 82742
109 + 82633 = 82742
151 + 82591 = 82742
181 + 82561 = 82742
193 + 82549 = 82742
211 + 82531 = 82742

Showing the first eight; more decompositions exist.
