Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82840, here are decompositions:

3 + 82837 = 82840
29 + 82811 = 82840
41 + 82799 = 82840
47 + 82793 = 82840
53 + 82787 = 82840
59 + 82781 = 82840
83 + 82757 = 82840
113 + 82727 = 82840

Showing the first eight; more decompositions exist.
