Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86530, here are decompositions:

29 + 86501 = 86530
53 + 86477 = 86530
89 + 86441 = 86530
107 + 86423 = 86530
131 + 86399 = 86530
149 + 86381 = 86530
173 + 86357 = 86530
179 + 86351 = 86530

Showing the first eight; more decompositions exist.
