Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82818, here are decompositions:

5 + 82813 = 82818
7 + 82811 = 82818
19 + 82799 = 82818
31 + 82787 = 82818
37 + 82781 = 82818
59 + 82759 = 82818
61 + 82757 = 82818
89 + 82729 = 82818

Showing the first eight; more decompositions exist.
