Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86508, here are decompositions:

7 + 86501 = 86508
17 + 86491 = 86508
31 + 86477 = 86508
41 + 86467 = 86508
47 + 86461 = 86508
67 + 86441 = 86508
109 + 86399 = 86508
127 + 86381 = 86508

Showing the first eight; more decompositions exist.
