Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82940, here are decompositions:

37 + 82903 = 82940
103 + 82837 = 82940
127 + 82813 = 82940
181 + 82759 = 82940
211 + 82729 = 82940
241 + 82699 = 82940
283 + 82657 = 82940
307 + 82633 = 82940

Showing the first eight; more decompositions exist.
