Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82886, here are decompositions:

3 + 82883 = 82886
73 + 82813 = 82886
127 + 82759 = 82886
157 + 82729 = 82886
163 + 82723 = 82886
229 + 82657 = 82886
277 + 82609 = 82886
337 + 82549 = 82886

Showing the first eight; more decompositions exist.
