Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82040, here are decompositions:

3 + 82037 = 82040
19 + 82021 = 82040
31 + 82009 = 82040
37 + 82003 = 82040
67 + 81973 = 82040
73 + 81967 = 82040
97 + 81943 = 82040
103 + 81937 = 82040

Showing the first eight; more decompositions exist.
